Hi,
Tested AC 7.25, Win7, aero enabled, extended borders = true.
With previous versions of AC, there was problem with missing borders in some situations when form was “always on top”.
Now it seems that there is “reversed” problem. Content of form disappears.
Also when form is closed, borders remains visible.
It is happening on another forms than main form1. (Main Form1 works properly, another forms, for instance Form2 has described problems).
Reproduce:
Just create two forms application, Form1 main form. Set “stayontop” on form2, show up the form2 (by button from form1). Form2 content disappears when another application is shown. Try to close form2 – its borders remains visible.
Disappearing of content has relationship with Application.MainFormOnTaskbar. Border problem is not related to this property.
