This might have something to do with the fact that OS-X double buffers 
it's windows, so you need to force and update event somehow. A call to 
wx.Window.Refresh() and/or wx.Window.Update() might do it. However, I 
haven't had any problem with just using a wxClientDC in my apps, but I 
guess I've always been running an event loop. Maybe OS-X waits for a 
Idle event to update the screen.

What kind of app would you have running without an event loop anyway? Id 
didn't think you could do much at all without one in wx.

wxPython-mac is built in Carbon, not Cocoa, but they do both use Quartz
