About MDI (Question 2)

I noticed that when I switch between MDI Child Windows (In Maximized state) it always cause the screen to flicker...
And if I'm not wrong, the Child Window's state actually changes from normal to maximize thus causing the flicker

Anyway to overcome this?

Don'rt really know 'why' this happens, but it will every time you open an MDI Child.  To stop the flicker, they this:

procedure TMDIParent.Button1Click(Sender: TObject);
begin
 lockwindowupdate(MDIParent_Name.handle);
 Application.CreateForm(TMDIChild_Name, MDIChild_Name);
 lockwindowupdate(0);
end;

Any questions, add a comment. Good Luck!
