RC2 - Debugging?

I just installed build 2201 (RC2) and now my VS2010 is locking up when I'm
in debug mode.  I start debugging, and the editor switches to debug mode,
but then is unresponsive.  The web site still works fine, as if there was no
debugger.  I have to terminate the VS2010 process from the Task Manager.

I haven't been able to prove that RC2 is the cause, but it would be good for
others to check this too.

I'll update when/if I can verify that Resharper is the cause of the problem.
