> 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 Are you running on XQuartz (http://xquartz.macosforge.org/) or the OS-packaged X11? XQuartz is definitely recommended. Can you also try running the demo in a Wine virtual desktop to see if that helps the issue? GLX on OS X has always been something of a moving target but it's getting much better. -r
