>i was just wondering, im creating an application which uses an mdi form, but i noticed something; whenever i open a form/click a control on an open form or even click the toolbar, the screen flickers;
>(the title bar, and the menu flickers)
>is this normal? or im doing something wrong in the code?

I never noticed that. Are you calling some special functions? Do you call the Refresh method of the MDI form? Do you have special code on the MDI form?
