Random Disconnects

[Casamar]

Most times when I use UB2 I lose my connection to the game - I get no error message, to my screen everything appears normal, but I have left the room, I just don't know it until my opponent messages me to let me know.

Other times for some reason I am able to happily play for hours with no problem.
I've tried playing in a browser and via downloading and installing the game. I've updated video drivers, my brower, java, basically everything I can think of, yet still the problem persists. I've been using UB for well over a year with no issues until just recently. It doesn't appear to be an internet issue as the skype continues fine with whoever I'm playing.

Any suggestions?
