@bb the size there is 16400 (or similar) which hasn't changed at all before all this happened and the don't move option hasn't been selected, all is as it was before this happened. I think it could have something to do with the windows 7 shields that have appeared next to delete and rename.
@ lisa, have created a document and set on desktop (if that's what you mean) but not sure how to send things to it, doesn't have specific names in send to. I admit to be non techy, I will try certain things but not good at doing much. Sorry, it must be difficult to advise someone like me.
