Leopard Spaces pref file causing a problem?

I have a question... I had Parallels running fine on my first launch after the Leopard upgrade ... I of course was playing with Spaces and moved it to a new location then quit and restarted my Mac ... Now when I open Parallels "unexpectedly crashed" dialog. NOw I have done everything I could think of (beta, following the workaround steps, uninstalling reinstalling) ... Is it possible that my Spaces pref file is causing a problem? Any idea where I could find that to test. Just not sure why it would work and then no longer work.

Thanks!
Bill
