DVDFab box is way up top of screen



Hi to all,
I am running a version of DVDFab 9, and have encountered an interesting problem.
The activity box, for lack of another name, is halfway off my monitor screen at the top. I can see the lower half maybe, but the rest is off screen high and I cannot figure out how to get it back entirely onto the viewing area.
At one time or another I have had the screen jump around when ever I attempt to move my mouse onto it, and can only close with the task manager.
Do I need to re-install, or is there a way to bring the box back down o9nto the screen?
