Thank you for your post.
Several people have reported a flicker problem. Many of those have corrected the problem by obtaining the latest video driver from the manufacturer. Still, some continue to have the flicker problem. I would try that avenue first, and if the problem remains, please let us know what video card and driver your customer is using.
Thanks for your response. I'll let you know after I've passed your info along to them so that they can have their IT check it out. I'm somewhat confused though about why it should show up after two years and nearly 3 months after the latest enhancement. It almost sounds as though something changed on the customer side
