Since yesterday a 2x2 millimeter blue square appears on the center of my desktop on the wallpaper as a last item to be loaded. It darkens when I click on it but nothing happens. Right-clicking does nothing. It has no properties nor any? function. It is just a small picture. What is it? I want to get rid of it. But how? Any ideas would be helpful.

First see if it does not appear in Windows Safe-Mode. A Description of the Safe Mode Boot Options in Windows XP Then if not, proceed with troubleshooting-- How to Perform a Clean Boot in Windows XP To find out what each Startup(or Process) item does or means, and any recommendation as to if you should close the process: Task List Programs Do you check for, and remove, Spyware ?? Spyware info.from Microsoft Virus and Spyware scans work better in Windows Safe-Mode.

BiggiVS, Righr click your Desktop, choose Properties, under the Desktop tab click the Customize Dwskrop button, under the Web tab uncheck everything including My Current Homepage, click OK/Apply/OK. Tufenuf

Thank you for your responses. The problem is gone. Here is how it was done: I scanned PC for intruders but found none. I magnified the "thing" on the desktop and found out that it was a nibble from the uppermost blue bar of some program that was loaded, but unresponsive when clicked on. Then I ran the Process Viewer that comes with Norton and there is a "process finder" in the form of a magnifying glass that I dragged over the "thing" on the desktop. The process found was the Kodak Software Updater which I then disabled using Autoruns and restarted. Bingo! Problem solved.

BiggiVS, Glad to see that you fixed the problem and Thanks for posting back to let us know how you solved it. It may be helpful to others that may run into a similar problem. Tufenuf
