I use synergy+ (1.3.4) for Mac (10.6.4) and Windows 7. Copying a content from PC to Mac works OK, the other way round doesn't work. I mean, the contents in Mac's buffer doesn't move to PC.
I think it's Mac's problem, as when I copy something in Mac (screen1), nothing is shown in the log, whereas doing the same thing in PC (screen2) report that clipboard is changed.
screen "screen2" updated clipboard 0 screen "screen2" updated clipboard 1 screen "screen1" grabbed clipboard 0 from "screen2" screen "screen1" grabbed clipboard 1 from "screen2"
What's wrong with Mac's synergy+?

I got the same issue again with Windows 7 64bit. I googled it and found that it's an open issue - http://synergy-foss.org/pm/issues/77
