No offense intended, but I don't even have the specific options named in the above text:
- No Show Office Clipboard when Ctrl+C Pressed Twice
- No Cut, copy, and paste option
- No EditCopy
- etc.
Actually, practically none of the specific named items are present in my Excel Options dialog box.
What I did eventually discover is that the problem was the text I was trying to paste into an Excel cell.
I had copied a line of source code from an ASP.NET web page of <script type="text/javascript"> from a Visual Studio code file and was trying to paste it into Excel. It just would not perform the "paste".
When I then tried copying another chunk of text (but not the same text), I could paste it into an Excel cell just fine. It seems that Excel does some kind of examination of clipboard contents before it performs the paste. Weird, this is the first time since Excel has existed that I have had such a problem.
Just wanted to let others know what I discovered.
