Btw, sorry for this reply-to-myself, but in case it's useful, take a look at this screenshot of the "penguin" wxWidgets demo (this screenshot belongs to the Linux build, but it looks very similar on the Windows build): http://www.wxwidgets.org/images/screens/penguinm.gif As you can see, the view is on the main window, and, as said above, you get this when you start this demo with wine 1.3.21 on OSX: wine[592] <Error>: unknown error code: invalid drawable wine[592] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged. set off screen: invalid drawable
