Somehow, the app has inconsistent tolerance for people who multitask - as l do for example between rounds in a tournament. Sometimes, l can cruise over to email for a few minutes before being booted. Today, however, l used no mre than three seconds to respond to a chat and came back to find myself offline (my hapless tourney partner was even more upset than l was!). I hope you can figure this out. If more precise information would be useful, feel,free to contact me. Cheers! David/chot
