Pokerstars: check and fold same key

[unt1]

now i testing all without HM2
with / without starshelper
with hotkeys_fire_on_release 1 and off
and all time i have auto fold



now we thinking about my PC is bad ?

i have i5 4570 3.2ghz and 8 gb ram
what is low?
I think the problem is that I quickly move the mouse and for some reason a hotkey is triggered in one click and on the next table under the mouse

I tried to set a real-time priority in the task manager

no more ideas
