By switching of auto arrange on the desktop I can now drag the icons from the top of the other icons. I now have two My Computer,Recycle Bin, and My Network Icons The ones I can drag I can also open The other set are fixed on my desktop and do not respond to any action from the mouse including delete. Any ideas anyone?
You were completely correct Simsy, although the one playing the prank on me was me.
Now that I have stopped laughing I will explain.
A couple of weeks ago I was selling my 17" tft on ebay, to help the sale I took a screen capture of my desktop which is a photo of a beautiful sunset taken from Seamill on the west coast of Scotland looking over to The Isle of Arran.
The screen capture was subsequently saved in the My Pictures folder and then in some way replaced the original picture as my desktop so the icons I couldnt move were part of the screen capture picture and the real icons were sitting over them.
I am glad this is being worked out over the Internet and no one can see my red face :-).
Once again a big thank you to Simsy for setting me down the right path.
