We have isolated a problem that causes PSA RC2 to crash when you are using it with Powershell Community Extentions. It seems that there is something in the code of PSCX’s start-tabexpansion cmdlet that bombs an error that’s not even able to be caught when called from inside PSA regardless of whether you call it in the profile or ad-hoc interactively. It also only happens with our protected versions of PSA. We will try to isolate what exactly inside start-tabexpansion is causing this and see what we can do to fix it. In the meantime I just suggest you editor your profile and #comment out the line that calls start-tabexpansion and all should be ok.
Sincerely,
The ShellTools Team.
