Thanks.
1. This is fixed already in the latest code.
2. Hmm, you're right - logged:
http://quest.codeplex.com/workitem/8553. Are you doing much editing in the code view? How long has the code view been open when the problem occurs? Would be great if you can figure out a scenario to reproduce this consistently. It might be just that we need to update to the latest version of AvalonEdit (which powers the code view).
