I really don't see any reason why that would happen. Can you talk about the problem a bit more? Do the hotkeys just not register and you have to press them again? Or are they just delayed and eventually do register after one press?
Does the problem only happen with 8+ tables? And fewer tables it works fine?
If you turn off "Activate table under mouse", do things improve any?
