Oftentimes when working in a spreadsheet after I select to paste something, doesn't seem to matter what, just a group of cells from one file to another, I get an error that there was a problem pasting. Then I can no longer click inside a cell. The only alternative I have is to save the file and hope it is okay when I reopen it. OR I could just abandon it without saving. Sometimes the file, after saving is fine. Occasionally I get a message that there is something wrong and do I want Excel to try to fix it. Sometimes this totally destroys my file. What a pain. Anybody have any suggestions. I did NOT write down the exact messages I get but I will the next time this happens. It happens just about EVERY DAY!
