Hi Alex,

Sorry, it took so long to reply :)

Yes, I see the effect. The only easy way to prevent this is to resize the titlebar window beyond the desktop, so it can't be click&drag with the mouse. But I don't know what else could happen (keyboard maybe ??)

Other than that you have to intercept WM_GETMINMAXINFO (hook/subclass). Intercept WM_WINDOWPOSCHANGING will not work.

Well, I wish you good luck!
Regards
