This is more of an annoyance than a problem. Sometimes when I close an application and go back to the desktop the picture has reduced to a quarter of its size and is in the top left corner of the screen, so I have to go into desktop properties, browse to select another picture, click apply then the desktop is back to normal. This only happens ocassionally and I am running XP home.
Yes it was set to stretch, I have know set it to center. IS their a known issue with having it sety to stretch. TO Proxy worm Ihave scanned with an up to date AVG and also an online scan which showed no viruses, lets hope taking it of stretch solves the problem. Thanks to both of you for your help. Regards ALAN.
Alan. Try opening up the folder where the picture you want to place on yor desktop is then without opening it, right click on it and choose "Select as desktop background" I don't think it will work but its worth a try. I'll keep my fingers crossed!
