Blender 2.57.1 r36812, Win 7, 64 Bit, Home Premium
I`m used to press STRG+ALT+DEL to call the task manager. In Win 7 you will jump to this blue selection screen where you can use what to do next, including to call the task manager.
Well, i had Blender open, it had a very low fps while playing an animation, and i wanted to have a look what is going on. And so i pressed STRG+ALT+DEL to call the task manager. But this time i was not sent to the blue selection screen. My pc was shut down immediately instead. There was no warning, no selectionscreen, just a pure shutdown. As if i would have clicked the shutdown button.
There is no error report generated, and no other hint what is going on. I have no antivirus software or something like that running in the background. So that can also not be the cause. It is repeatable here though, also with an older build. My pc will shut down immediately every time i press STRG+ALT+DEL and Blender has focus. Something that does not happen with other software. Here i get the normal blue selection screen.
I`ve asked at the german Blender forum if this happens to somebody else. But so far nobody has the described problem. At their pc everything works as thought. Makes me scratch my head what is different at my PC or Blender installation. Well i have tweaked the UI a bit. And have changed the hotkeys too. Maybe there lies the reason?
I have exported and attached the keyconfig file. That`s all i can offer for now. But I got a error message while export. So not sure if it is of any use. That`s worth another bug report i would say ...

Hmm, wenn Blender die Grafikkarte für die Animation benutzt vielleicht ist sie etwas zugestaubt und überhitzt deswegen?
(Maybe your graphic card is too hot because of many dust in it.)
Nice idea, but it is definitely no heat problem. I can start my cold PC, open a blank blender, press strg+alt+del, and my pc shuts down. As told,it is repeatable, and happens just when Blender has focus :)

That is very strange.. did this also happen in earlier versions or is it a new problem? You can also verify if it's related to the changes you made in user preferences, by selecting load factory settings from the file menu (doing this does not actually write anything to disk, your settings will come back next time you open Blender).
Thanks for the good advice Brecht. Haven`t thought about this before. It also happens with the factory settings.
Hmm, i have checked with the oldest build i have here at this pc now. That`s a 2.55 release, r33080. And here it does not happen. The 2.57 releases seems to be affected though. So the answer is a clear yes, this is a new problem. Introduced between 2.55 and 2.57.
I'm unable to reproduce this with win32/win64 blender 2.57b releases nor with current trunk (win64).
Note btw that you can get directly to the task manager with ctrl+shift+esc (strg+shift+esc).
Ah, these are the meanest bugs. You can of course just fix what you are able to reproduce. All i can say is that it happens with all the 2.57 builds, but not with a 2.55 build. Curious but true. There is something in the 2.57 line that conflicts here. Which means that it is not my pc in general that went wonky, and not a special single Graphicall build neither. Hm. I´m as clueless as you now.
Maybe we can find out the cause when this bug gets rereportet by somebody else. Maybe this behaviour even disappears with one of the next builds. Knockin on wood here :)
>Note btw that you can get directly to the task manager with ctrl+shift+esc (strg+shift+esc).
Thanks for this hint. You never stop learning :)
Some things doesn`t let me rest. Have it!
I have made a shortcut to the shutdown,exe at my pc. It contains a hotkey combination to shut down my pc immediately by a hotkey. So no need to dig with the mouse in the startup menu to shut down my pc.This shortcut resides at the desktop.
The shortcut contains the following string: C:\Windows\System32\shutdown.exe -s -t 00
Hotkey combination STRG+Alt+ (extra key)*
Executed in: C:\Windows\system32
*This extra key does not show up in the shortcut. It`s a extra on/off button. I have a cherry keyboard with some custom keys here. Seems that Windows 7 does not like to show extra buttons.
Well, long story, short end, everything works as thought when i remove this shortcut.exe from my desktop. Hm, makes me wonder why strg+alt+del calls my shutdown.exe when Blender has focus.
I have attached a screenshot to show what i mean. I would`ve attached the whole shortcut too, but i was not able to zip it, heh :)
Hm, got a error message when i tried to upload the image. "missing parameters" . So no image, sorry.
To upload image, make sure you have the file attachment tab visible when pressing "save changes" (as the note above the input fields says too ;)
But good that you found out the root cause for your problem. I guess we could close this bug though.
Thanks Nathan :)
Well, it`s still a bug. Even when it just happens to one of a million :D
This shutdown behaviour does not happen with older builds. But with 2.57 it does. So there has something changed. But yeah, i have my workaround :)
I`ll try again with the image now ...
Hm, the attachment tab was definitely selected this time. That`s where i upload the image. But i get the error missing parameters. And with a second try the warning of a double post. Something`s wrong here.
Okay, then by Image Shack :)

The main change between 2.55 and 2.57 is that the command terminal hides on startup.
But further I wouldn't know any clue... maybe nathan finds time to test this shutdown.exe in his config (assuming it's a standard windows option).
Thanks Ton :)
This shortcut is no standard Windows feature. It is made by hand. It`s not absolutely uncommon though. There are several tutorials in the net how to create this shortcut.
Hm. From a standard windows setup angle of view i would say close the bug report. From a user`s angle of view it would still be interesting to know why this desktop shortcut gets called from within Blender. When this desktop shortcut gets called by accident, then theoretically other desktop shortcuts could also be called by accident :)
I did a quick test: Open Office Writer uses Ctrl+Alt+N to insert a comment. I created a shortcut on my desktop and assigned it also Ctrl+Alt+N. With Open Office as the active application Ctrl+Alt+N triggers the desktop shortcut by starting the assigned application, instead of triggering the comment action in Open Office Writer as expected.
My impression is that these shortcut hotkeys are global, and probably not something one can do much about.
