So from this it sounds like the module may not be too flash on Win32 or Mac.
But surely as Max is supposed to be cross-platform, the GUI module needs to provide the same functionality on all three platforms? Can't really see how that's going to work with a GUI as each system has it's own native style.
I'm looking forward to the GUI module but I'm also reserving judgement until I actually the same code running side-by-side on my PC and my Mac.
