is this only happening when you play tournies. Have you tried playing cash to see if it happens on your computer. I haven't experienced it at all playing titan , but aside from depositors/vip freerolls i havent played any tournies its all been ringgames.
Have you tried using the flash browser client at chili or titan. You load it from the main tuitan page and under the big red dowland icon theres and instant play link (also lets mac/linux users play on ipoker)
