Hi,
As I know, VFPSkin set form.TitleBar = .F. and call WinAPI to "paint" the "title bar" on form. VFP treat this "title" as something else rather than the real titlebar. Therefore, I feel it is not possible to do what you wish at this moment.
HTH
I am not the most powerful man in this world.
I am not the worst man in this world either.
I just as same as all of you.
I still need to learn from my mistakes...
