C# Window gets blank when busy -> Progressbar? But how?

I have a program which does some copy jobs (via File.Copy) that could last a few minutes. When the user brings another window to foreground in this time the program window gets blank since it doesn't redraw itself.

Now I want to show a ProgressBar in an extra window in the center of the screen, but that window get's blank too.

So I startet it in another thread which didn't help.

I'm quite sure someone did this before but I cannot find a working example. Any Ideas?
