Stopping Poker Tables from Popping up

[Hitsurume]

Hi everyone

I've been playing at Pokerstars, and I don't have a good enough monitor for high resolution, so i'm wondering what programs or software can I use to prevent stars tables from popping up?

Everytime i'm 2 tablign and trying to make decisions, the other table pops up and interrupts me, kinda hard to work with =\

Thanks

Hitsu
