Comment 9 for bug 875170

I can confirm that any window overlapping the right edge, allows synergy to work. Maximised windows do not - perhaps as they don't go over the edge. Regardless, I can always get to my other screen to right by putting the mouse cursor to the top, over the top panel, and then move right (as others have noted).

Even more weirdly, moving my 'enabler' window away from the right side, does not immediately stop synergy working - it takes a moment (a second or so) to stop working.

Setup: Ubuntu as the server on the left - A Mac on the right as client.
