**System Information**
Windows 8.1 Pro
i7-4790 CPU @ 3.6GHz
16 GB RAM
GTX 770 2GB
I built this computer myself.
There are two monitors:
Primary: 2550 by 1440, arranged on the right. Connected through DVI to my Graphics Card.
Secondary: 1920 by 1080, arranged on the left. Connected through HDMI to my Graphics Card.
**Blender Version**
Broken: 2.75a
Worked: N/A
I tried 2.57b to see if the error was present back then. It didn't crash blender when I closed the User Preferences window, but when I later quit Blender, it would crash instead of exiting normally. This crash did not happen without first opening the User Preferences window.
**Short description of error**
Opening User Preferences from the file menu and then closing it crashes Blender. When I opened it from the command line, I saw "Error: EXCEPTION_ACCESS_VIOLATION" appear at the moment that the close button was clicked. This also occurs if I open a duplicate window with Window->Duplicate Window; closing the new window triggers the same crash and error message.
I open Blender with --factory-startup, and the results are the same. I have also tried both the .zip download, and the installer version, as well as deleting the Blender Foundation folder in Program Files and installing fresh. I also found a [[ https://developer.blender.org/T44626 | bug report with the same apparent error ]], where someone posted a software OpenGL DLL. It did not fix the issue (but the UI was slow, so I know I used it right). [[ https://developer.blender.org/T42464 | This bug report ]] also appears to document the same issue, though on OSX.
The issue does not occur in a Debian VirtualBox instance, on the same computer. I could also not reproduce the error on a different computer, my MacBook.
Here is my system-info.txt: {F206768}
Also, this may not be relevant, but when I open Blender from the command line, I get the message "AL lib: (EE) UpdateDeviceParams: Failed to set 44100hz, got 48000hz instead".
**Exact steps for others to reproduce the error**
Open User Preferences window, close User Preferences window. Error occurs.
