No.

I just realised what's probably causing that - we use our own version
of wxGridCellTextEditor, which uses the STC instead of a rich text box
to avoid some bugs. Because we haven't implemented our own version of
EndEdit() yet, it's probably assuming the edit control is the original
type in the default code.

That's working fine.

Will do. I'm actually OOO for the next few days, so I'll try to look
in the evenings.

I've never seen that effect in any other apps that I can recall. Plus
the toolbars do have a text style to enable/disable labels, which is
off by default.

Yeah, that was my thought.

Ahh, ok. Didn't get as far as searching for that yet - thanks!
