I've been having the same problems as above. I am 200% certain I've followed every instruction given by Opera on synchronisation on both my laptop and desktop (5 times over). I hope somebody at Opera is looking at this thread. I'm not going to bring this to their attention directly. Why? I expect that they'll simply take me through the whole process again, then blame some virus shield or something. How? This is what all organisations do, instead of investigating their software more carefully at the outset. So I do not have an hour of time (or more) to spend on this.
