I have been having trouble with my VS2010 restarting when I have instructed it to exit. The restart is caused by VS getting an error during the exit process and that then invokes VS to restart. This is very annoying - hard to shutdown VS2010!! Disabling only VAX (build 1925) removed the problem.
This is information from the Application Error Log on the VS2010 crash:
I think the problem was related to the VAssistX toolbar. It was scrunched up in the top right corner of the top toolbar row. No icons were visible in it.
I didn't even know there was a VAssistX toolbar. So when I found out about it, I moved the toolbar so I could see the icons and then tested if VS2010 crashed. It no longer crashes (even if I scrunch up the toolbar again).
