Works fine for both 2.56a Official release and current trunk r35406 on Windows (32bit and 64bit).

I'm on a Windows 7 machine with 2 ATi HD 5550 cards.

(typo fix in title)

Thank you.

Well, I will try to repeat this error on a computer with Windows Vista and Nvidia graphics card, this evening.

If it will be OK, then it may get the lowest priority (Windows XP is outdated)

Moved from Blender 2.5 Bug Tracker to OpenGL errors

This is an on-board intel graphics card, for which we received a lot of reports already.
Users of Nvidia or ATI and the other OS's don't have this issue, which points for now at a driver issue...

There's been a recent fix in our code that could help for this case too though. You can download a test version from graphicall.org (at own risk :) or wait for us to release the 2.57 version end of march. Please feel free to post in this report updates on the issue, we get emails then.

Thanks!

(moved to opengl tracker)

nazg-gul seems to fix the problems with Intel cards on Windows. Thanks!

May you check the new build for errors on your system? And report any problems. Thanks.

Thank you!
It seems that there is no more the r36070 today (the file linked in previous post is no longer available).
I have tried it with newest r36091 (BTW. its ZIP at builder.blender.org was packed with the 2.56 subfolder nearly empty - I had to copy one from previous builds)

Result - negative!

The errors, described above, still occurs.

I just verified the .zip from builder.blender.org for r36097 (currently the latest), and it has the 2.56 exactly as it should be. If you could check with that still.

Thank you.
I have tested with r36097

The result is still negative - File->User preferences crashes Blender.

Should I deliver any additional information, which would be helpful? I am able to open the crash point in a debugger, but, of course, I can see only the assembler code there.

You can never give enough info... and confirm that r36097 was from builder.blender.org site?

A full stracktrace can just be attached here!

Full stacktrace probably doesn't tell you much interesting from release builds (and the results you do get are potentially unreliable) :)

@nathan: I suppose :). Will just check for driver updates -

Yes, it is the file downloaded from builder.blender.org (blender.exe, file size: 19 888 640 bytes, created on 2011-04-11 06:03)

OK that stacktrace only tells the crash in the driver.
It's XP... could you check intel.com site for driver updates?

I have updated graphic driver to the latest version: 2.1.0 - Build 6.14.10.5337
(published just a few weeks ago)

Blender still crashes on File-->User Preferences.

It seems that this time crash occurs when the frame of the new window appears on the screen (without any content). (I am not sure at this moment, but with original driver the frame of User Preferences window was not visible)

Resolved!
In 2.57 (build 36147) works properly!

Thanks a lot, guys, to take care for such old system like Win XP! :) :) :)

Unfortunately not resolved for me. I downloaded 2.57.1 - r36339 and I still get this crashing behavior regardless of using File->User Preferences or Ctrl+Alt+U. A black window appears and Blender stops responding immediately. I'm using Windows 7 with an "Intel(R) 82945G Express Chipset Family" adaptor.

@M H:
Have you updated your drivers to the most recent version?
I did it with my XP - sometimes the factory installed system uses their older versions.
Estimating the frequency of driver versions releases on the Intel page, they still are fixing their bugs!

I also have this issue.

Blender crashes on File-->User Preferences

OS: Windows 7 (32 bit)
Blender version: 2.58.0 r37702

The APPCRASH output indocates that the fault module is a Dell video driver (ig4icd32.dll).

My machine has the latest version of that driver (8.15.10.1855) and the driver has not been updated (maybe ever).

As an aside, and not wanting to throw in a red herring here of offer up a third party app as the culprit, but I'm "pretty sure" I was not getting the error when I originally installed B on this PC. It was v 2.57 back then. However, whilst using 2.57 the problem started, and I had installed other software since 2.57. Notably, OpenCV, and cygwin with a shed load of additional options. I'll post an update if I make any discoveries...

Meanwhile, Blender's crash dialog:

I am running Blender 2.69, so I guess it came back. :(

I accept that you cannot address every bug in every version of every display driver.
I even accept that this issue is caused by a bug in the display driver.

What I wonder is:

• what does "File / User Preferences" do that no other aspect of Blender does that causes this driver bug to crash the app?

WORKAROUND:

• instead of "File / User Preferences", click the "Editor Type" button in the 3D view area and select "User Preferences".

SO, what does "File / User Preferences" do that "Editor Type / User Preferences" doesn't do?

PS: I have the latest drivers (2009) from Acer (manufacturer) and Intel (chipset) and the issue persists.
(: Yes, this is an old laptop: Acer Inspire 5732Z running Windows 7 Home Premium 64-bit :)
