This sounds very strange. Please explain in detail the clicks you do to copy data.
Are you copying files or data within files?
Example:
1. I select a text file (me.txt) from Drive C: and copy it to drive D:
2. The file does not copy to drive D: but the text in the file is now merged in me.xls
My copy and post usually consists of
1. left click hold and drag to highlight area to be copied
2 right click and select copy
3) move cursor to are where I want the data to be pasted
4) right click and select paste
The copies work but the data remains on the clipboard.
I can't be sure if the initial paste copies the data to the spreadsheet while the file is closed but I suspect that somehow another operation causes the copy againafter my wife opens the spreadsheet.
It's happened a couple of times in our excel budget spreadsheet which my wife does. She swears she does not do a right click paste operation. I have tried to duplicate the paste by hitting every key to no avail. A right click paste will do a copy
It doesn't have anything to do with the source of the copied data since it has come from facebook picture which ended up in an email, an Itunes list of podcasts to a thumbdrive and an email web address from an email to paste in the address area at the top of my browser. The latter 2 appeared in the excel spreadsheet.
I checked the net and found a stop-gap solution using a command that clears the clipboard before using the excel spreadsheet. We'll see if that helps.
