This happens frequently, and I'm not quite sure why... or what a quick fix is.
I play 6-8 tables of Rush. When its time to stop the session, I sit out next hand on all the tables. And then when I try to close the tables or exit Full Tilt, I have to press cancel the Get Chips window, and then I have to close the empty table. This happens for every table.
Clicking the 'x' on the lobby just brings one of the tables to the top. Its twelve to sixteen extra clicks that I'd like to stop doing. Common bug, or am I just closing/exiting incorrectly? This scenario happens frequently, but not every time.
