Top panel in Xinerama causes loss of second monitor desktop space
Last modified: 2004-12-22 21:47:04 UTC
Using the default top panel that came with 2.3 and Xinerama leaves a area exactly the size of the top panels dimensions unusable on the second monitor. See screenshot for more info.

I should have added this before - What appears to happen is that the panel on top of the default display doesn't allow other windows to exsist on top of it, and though it doesn't carry over onto the secondary display, it behaves the same way in the same area that it would exsist should it cary over. So, just like in the default display, you can't move windows past the 40 or so pixels that the panel occupies.
Yes, this is a known issue ... it needs to be addressed in the window manager. *** This bug has been marked as a duplicate of 86682 ***
