If you are encountering frequent VS 2010 crashes when you
are typing in the editor while Intellisense is popping up and/or being
dismissed then you are running into this issue.
Why does the crash happen?
The most common cause of the crash happening is that you are
running a machine that:
Is a Tablet PC (even if you aren't using the pen)
Has multi-touch screen drivers enabled
Has an external input device like a pen or Wacom tablet
Has a screen-reader enabled
It turns out that a late fix right before the RC shipped
modified a UI input code path that unfortunately exposed this bug.
A patch is coming to fix this issue
We are working on shipping a VS 2010 RC patch that we’ll
release next week that will fix the issue and prevent it from occurring.
I’ll blog a pointer to the patch once it is available.
How to work around the issue now
There are two ways you can work around the issue now.
One is to disable your Tablet services (read
this article for details on how to do this) and/or disable Multi-touch/Pen
drivers on your system. The other is to set a registry key.
You can read about both of these workaround in this VS Team Blog Post.
