Thanks! I'm right in the middle of fixing this one actually...turns out .NET TextBox KeyDown events are bugged in max (ESC causes crash in some circumstances, as you see)....it's a legacy issue I didn't know about until today.
Fix for this will be up with the next build, which I'll be posting in a few minutes.
