I'm guessing that there is a Freeze() that didn't have an associated
Thaw()... Did you run from a terminal so you could see if there were
any exceptions? That could be one reason that a Thaw() got skipped.

Luckily I only found one Freeze/Thaw pair in XRCed, so that was an easy search.

The problem seems to come from calls to a notebook's RemovePage method. It's in between the Freeze() and Thaw() calls. The Thaw call is still reached, but just doesn't seem to do it's job. If I disable the RemovePage calls or move the Freeze() below it, the problem goes away. All this happens without an exception in sight.

The code can be found in the AttributePanel module, starting at line 130 (the SetData method).

For now, I've "disabled" this problem so I can get on with my work, but I'm starting to expect that I'll run into other 'quirky' behaviour because something went wrong when I built wxPython 2.9.

To be continued...
