Screen blacking out

Submitted by david1904 on 2011/07/01 05:52
I've noticed that InfoQube is prone to "blacking out" for 1-3 seconds at a time.
Its not just InfoQube - the whole monitor blacks out. It doesn't happen with the multitude of other programs I run - only when IQ is open. It is worse when IQ has the focus.
Sometimes there is a faint flickering of the IQ window. Whenever I move the scrollbar, click on another item etc. I get a run of black outs.
Is it a conflict somewhere with a driver or ...?
Anybody else have this problem?
I'm running Win 7 64 bit, dual ViewSonic monitors, Nvidia graphics card.
Thanks,
David
