Im not sure if anyone already mentioned this, i didnt have time to check all 176 threads, but when i play aces high, sometimes my mouse locks up. it only seems to happen in the tower though, and none of the three patches have fixed it. I have found that to fix it, i must unplug my mouse and plug it back in. I am not the only one with these problems. I have heard several other people in the training arena complain of the problem and i told them my solution, which worked for them too. Its not the most debilitating problem, but it gets rather irksome.
