Pokerstars Question

[tradenine]

I am multitabling on Pokerstars... When I click a button on any table not "in front" - that is, any table besides the one with focus - I have to click the button three or four times in order for it to work.

Whether I am clicking 'fold', 'check', the advance 'fold' checkbox or whatever, it doesn't matter: I have to make three or four clicks of the mouse in order for the action to be taken. It does not do this on Full Tilt. This is driving me insane. Does anyone know how to fix this problem?
