for aggeees now.. it's pissed me off

i open up a tab.. grab my guitar and begin learning..
the very moment i scroll down evern the slightest amount.. i mean the wind cuold blow the mouse and it happens... a full screen size pop up appears and it's completely blank and plain white.... sometime i only have to click once and it happens...

sometimes it doesn't happen at all but most of the time it does...

i was wondering if it happens to any of yuo lot?... it seriously pisses me off
