Anyone else got two-monitor issues with LC9 on Mac?

I should have also noted that I didn't see the problem with a small
misalignment of the tops in the Display Preference Pane; the tops had
to be quite far apart. Also, what was strange was that just because
the additional monitors may have been set to above the central MBP in
the Display Preference Pane, it didn't always result in an 'offset
high' situation - the Click occurring above the visible position of
the Mouse. Sometimes it was offset high, sometimes low.
