I'm unsure what may have caused this problem, but whenever I attempt to "Copy" (CTRL-C) cells, there are no "Marching Ants". When I attempt to "Paste" (CTRL-V), it does not paste the functions, column widths, formats, etc. When I right-click and go to "Paste Special", it only indicates that it is text.

When I first discovered this problem, I attempted to open other Excel spreadsheets and create new ones to see if they were affected. They were, so that lead me to believe it was a problem with the program itself. I first initiated the "Repair" feature for Excel, and it worked at first. The Copy and Pasting functionality was back to normal for a few moments until it suddenly only copied values again. I then tried to uninstall and then reinstall the program, but that did not remedy the problem.

Now I do press the CTRL key often since it bound as my "Talk" button for another program I use to communicate with my friends. If anyone has seen this problem or knows how to fix it, please let me know. Thanks.
