once, i was in a tournament, and my interface locked up for over 5 minutes right in the middle of a decent hand. figuring it might have been a connection issue at my end, i closed the window and logged back in only to see that the lobby was frozen too with several interface reboots. then i tried rebooting my PC and after about 10 minutes, i finally got back in only to find out that SOMEHOW, at the beginning of a tournament, i got knocked out in under 20 minutes. that was very annoying.
today, when i wanted to see if i could make a late entry to the jackpot freeroll, and got blank screened at the lobby too, and rebooting 2 times didn't solve the issue either.
what REALLY annoys me about ACR is in EVERY tournament i play, i get reseated around the 100-130 player mark and my stat screen goes blank. i count on that info to know if i need to play aggressive to catch up or tighten up to avoid a KO. the info is also available in the lobby, but toggling is a pain, especially if play is fast. it drives me nuts. switching back and forth between the chat window and stats window will cause blanking too and no amount of clicking on the stats window will bring it back.
