This appeared after wxWidgets introduced a ScrollHelper Class. See the
ChangeLog entry 2008-07-24

"The component tree stopped working on Linux and OS X after wxWidgets
implemented the wxScrollHelper. Although not fully fixed, it works
acceptable again. The main problem is, that it seems to be impossible to
have a scrolled window without vertical scrollbar. For now ignore the
bar in the middle of the component tree."

I tried to fix this, but my knowledge about GTK was too limited.

Works fine here, using an unusual environment (andLinux).

Sounds like a previous bug to me, which should have been fixed. I'm
currently running 2.0.7, linked to wxWidgets 2.8.4. May be I should
update my wxWidgets on the andLinux machine...

Sure, you are using the code from Ethernut's CVS HEAD? I can also
provide a source package, it that is more convenient for you.
