Steps to repdouce:
1. Install PSCX for PowerShell (http://pscx.codeplex.com/).
2. Run the PowerShell shell in Console2.
3. Import the PSCX module. (Insure that this succeeded.)
4. Run the 'help' command.
5. Watch Console2 freeze and crash.
Stability is pretty good otherwise; this is the only crash I've experienced so far!
