Hello, Alexander! By the way, how did you do that subject glitch? I do it in the CreatePen(PS_SOLID,1,1) loop - after they are completed (when it starts return error) the interface is glitchy, but not as bad as yours... Best regards, Evgeniy.

I am reading msdn-2002-06: Remarks You must destroy the icon handle returned by ExtractIcon by calling the DestroyIcon function. PS I suspect that any handles (for example, file ;) may run out. And any Windows will crash. Because IMHO in the case of, for example, hFile, their kernel cannot Is it somehow safe to limit for the user... Best regards, Evgeniy.

Windows crashes faster and more fun if you open a new one in an endless loop window. At least that’s what was written on the forum, I didn’t check it myself :) Alexand
