access violation using wxTreeCtrl

[Harry]

Vadim,

Yes, I'm using Vista.
Curiously, the abort happens in TV_SetItemState()  as it does for the 
patch you referred to,
although the circumstances look different (I'm closing the window).
Where can I get this patch ? Or do I simply download the last daily build ?

For what it may help, here's my stack trace with symbols (using 
wxMSW-2008-03-04):
