Main (parent) window freezes when Pop-up window is up

Hi, all,

        I have a "Waiting message..." window which pops up in another Thread. It works but not perfect as expected. I change Opacity of Main window (say .35) when waiting message window is popped up and change it back to original when whole process (usually it takes about several minutes) is done. However I find main window totally freezes and even worse it leaves a movement path of pop-up window if I move it around.

       Any ideas? Thanks a lot.
