I have experienced this issue since using Manager starting April 2015. So its not a version issue. It happens when I am scrolling up, scrolling across etc. I notice most in inventory where I have a lot of line entries. The example above occurs when I go into inventory, select something like Qty on hand, wait a few seconds and then hit the back button and I see the above pic. Of course it does not do it everytime!
I have windows 7 32 bit and I use Firefox, but obviously have IE 11. I noticed that my accountant had the same problem once when I went to see her and she had my books open on the screen. I don’t remember what operating system she had.
The issue seems to occur if you wait a few seconds before scrolling up or down and it does not do it every single time. Its very random as to when it does it. My belief is that it is some kind of refresh issue, so maybe its some wierd conflict with certain video cards, or certain screen refresh rates or screen resolution sizes I don’t know. I use 1280*1024
