access violation using wxTreeCtrl

[Harry]

Vadim,

Yes, you get the same abort when using the menu items in the "Style" 
menu (Toggle hidden root and Toggle selection mode),
but then you also get erroneous asserts and have to answer No to continue.
(These asserts were already the topic of an unanswered  previous thread 
of mine.)
I suggested modifying the sample source for treectrl in order to get a 
cleaner test.

Regards
Harry
