Hidden Ball watermark in my explorer window.

Hello all:

What I have found is a hidden ball watermark that is only visable when drawing a box around a group of files (selecting them for a copy etc.) . When you look at the window nothing is visable, it's just a plain white background. Further more this hidden ball doesn't appear on all the mapped drives. Only our new server's maped drives. This ball is located in the lower right-hand corner of the screen and looks like a clipart image. I have done a screen capture and printed it out. The ball is plainly visable on the printed page but not the screen. Has anyone ever seen anything like this before? What is it? Virus? I've been in the IT field for 23 years and havn't seen it's like before. I have attached the screencapture in a zip file for you to see for yourself.


Thanks in advance.

 

It is called a Watermark. Visible, due to you are not using Classic, and there are picture documents in that folder. Nothing on the lines of a virus, or unknown. And let me guess, all machines are XP, and the servers are W2k3.
