Beta 6 Hangs Indefinitely on Project change

[ken.strickland]

I have a problem with Beta6, where it now hangs when I change to a certain project.  I was happily working in this project earlier today, and now when I switch to this project it hangs and never returns.  Here is my Windows output of the hang when I forcibly close it:

Is there anything I can do to provide you with more info?

Try renaming your <workspace>.vpwhist file to something else. It could be hanging restoring files.

Yes, renaming the <workspace>.vpwhist file solved the problem.
