Flashing Windows - With video evidence I've tried googling this, but due to the words i'm using to describe the problem, I only seem to get hits about Windows, Adobe Flash, or 7-zip. When certain programs are running, they will flash out, and in again (as though disappearing, then reopening instantaneously) when left clicked. When the program is not in full screen, the desktop (or program behind it) will be seen before it flashes back up, or if it is in full screen, it will flash to black. When this happens, the left click is often not registered by the program. Also, most, but not all of the time when one of these 'flashes' occurs, the icon for the window, on the task bar, will do much the same: Appear to have closed, then reopen a moment later. Here, however, the icon sometimes does not come back, and will only reappear when the actual window is clicked once more. So far, I have experienced this in -Adobe Flash CS4 Professional - When creating animations/viewing animations etc.Most programs which make use of 3D graphics; such as 3D games. Any advice?
