Application freeze during resize ..

Dear all,

I'm building a rather complex application using
wxPython2.5.1.5u on WindowsXP/Windows2000.
The main frame is a wxMDIParentFrame split into two
parts by using a wxSashLayoutWindow (just like in the
wxwidgets demos). The left part of the frame containing
a notebook holding tree ctrls and so on.

While testing the resize behaviour in a rather extreme way,
i.e. resizing the main frame as thin as possible (i.e. only
the window title stays visible the application freezes after
sometime. Does anybody has any experiences how to make a workaround
or else ?

Thanks in advance,

Hannes Grund
