Hi Bob,

"...The new control does, however, clear the 'center frame' box in the
'display CCD frame' in the tool bar."

I was about to reply that if you move the CCD frame, the 'center
frame' box _has_ to be cleared. And this is true; but the control to
rotate the frame doesn't need to clear the 'center frame' check-box.
I've fixed this. In the course of doing so, I realized that some
other odd things could happen if you had the CCD Frame dialog running
whilst doing these mouse-click adjustments: the angle and other
check-boxes weren't always updated properly. I think I've fixed
these problems as well.
