Summary: wxScreenDC doesn`t work

Initial Comment:
not work at all, in wxSplitterWindow and wxAui also( sash and aui highlight ), but the same code perfectly work on win32.

after .Blit from wxScreenDC i have assert: 

/Paradigma/Developer_2/sources_Third_Party/wxWidgets/src/common/dcgraph.cpp(760): assert "wxAssertFailure" failed in DoBlit(): Cannot Blit. Unable to get contents of DC as bitmap.

I use Intel-Mac 10.4.4 and wxWidgets 2.8.0, P4 3.0HT, ATI Radeon x550, 512M,

for wxWidgets 2.8.2 it doesn`t work also

I have attach screenshot of xcode debugger window on assert

blitting FROM the screen is not supported when building using Quartz
anymore right now (workaround would be to set this to 0, not using graphics
either), I thought I had adapted wxSplitterWindow to use the wxOverlay
class which is the substitute for these situations, I'll have a look at it
as soon as I get the time to do so

Thanks,

Stefan
