Cubase 7.0.7 Window cascading problem

Hi all!
I have a small problem with one of my windows behaving strangely. Maybe you can help…
After I opened the Drum Editor window on one of my projects I noticed that the title bar at the top is hidden “underneath” the main Cubase title bar at the top (I’m running Cubase windowed over 2 monitors), and I can’t find a way to interact with it to move it. I can maximize it and get access to the Drum editor functions at the top, but when I restore it down to a window again it hides up top.
Is there some way to move that window without access to the title bar?
I have tried changing resolutions & single/dual monitors.
Any help would be appreciated.
