Sorry for my bad english
It's an old message, if you've solved it, just ignore it.
In the winecfg program, open the page "graphics" ad uncheck
"allow the window manager to control window"
I have solved in this mode.
If anyone can confirm for others too.
Yes, this works. Tested both on WinOmega and Delphi.
Thanks
