I wonder why it's always the Mac versions that need special treatment. Be it Java, Mono, WxPython. It works fine on Windows and Linux, but you have to do all kind of weird stuff to get the Mac things working (if you or your testers don't lose interest before it's done).

I have my own check boxes and radio buttons (using the regular ones+labels) to get those suckers colored properly... But coding everything again is kind of ... counterproductive...
I wonder if Poser faces the same problem with the numeric inputs for the dials... Those also pop up another input after clicking... maybe the regular numeric input is resistant to background color changes, too, like wx.lib.masked.numctrl... ;-)
