Virtualbox Para Windows 7 32 Bits

The appication frame locks it into my monitor window (edge to edge, full frame) but when i click back out of it, my ind window is still missing the top part of the frame. (no green, red, yellow buttons to touch). I figured there was a simple key command or setting to re-center the window. Really cant believe that once a window sticks partially outside my laptop window i cant get it back. I have to go into prefs/display/arrangement and move to side-to-side to fix it. I currrently have it top-and-bottom because my external monitor sits above my laptop screen on my desk.
