VB6 App running under MAC OS X + Wine

Hello,

I got my vb6 app working with Wine perfectly, BUT the only problem seems to be with Visuals.
Sometimes some buttons / lables seem like GRAY when the form loads.

If I drag & move the window off the screen borders, then the visuals Update and all goes fine? :/
It's as if AUTOREDRAW is OFF...

I'm currently experimenting to see if doing a form refresh or individual control refresh solves the problem.

Does anyone have any idea or setting perhaps under Wine to fix this?
