Kelly, Go to your Control Panel and click on Display. From the Display Properties screen select Performance. What is the Hardware acceleration setting? If at Full back in down 3/4 and give UFT a try. If this helps then increase it until the problem comes back. Back it up again a bit or just leave at a lower setting.
If it is already at a low setting, then it may not be the reason. I did do this with a new computer and did stop the problem.
