Dual monitors: partial menu bar missing
Using a MacBook Pro, hooking to an external monitor, not mirroring, separate displays on each monitor. At 1920x1080 resolution I get only part of the menu bar on the external monitor. Specifically the apple & the name of the program are cut off and the menu bar starts at File; no trace of the missing parts of the menu bar on the MacBook display.
Using 1680X1050, I get the entire menu bar on the external monitor but I keep getting messages to switch to 1920x1080, which does look substantially better.
Suggestions on how to get the full menu bar? [I have already reset all the disply settings, restarted the computer, fiddled with the arrangement and moved the menu bar from the small box to the bigger box twice.]
Thanks!
MacBook Pro, Mac OS X (10.6.7)
