Hi- Just got a new laptop running windows 8, I'm struggling to get used the different layout at the moment!!!

When I try to play a game which needs key presses whilst using the mouse pad, the pointer freezes in place and will not move until the keys are released. It even does it when in normal use whilst typing this???

Ive tried to find the "disable pointer whilst typing" option in mouse preferences, but cant find anything that gives me the option??? Its a Synaptics touchpad v7.2 and all seems to work well apart from this.

Anyone got any ideas????
