+- On SGI IRIX 6.4, XtDestroyWidget in ~wxWindow causes a crash in
+ some cicumstances. This is being looked into. Meanwhile, a
+ possible workaround is to remove the final XtDestroyWidget line in ~wxWindow
+ (window.cpp). This will mean that child windows will only get
+ destroyed when frames and dialogs are destroyed, so dynamic subwindow
+ deletion may not work properly.

+- There are reports that scrolling can cause crashes under Lesstif.
+ This is probably a Lesstif bug.
