Moving contents of cells

About half of the time when I move the contents of a cell I get the message "The Clipboard cannot be emptied. Another program might be using the Clipboard" Can anyone recommend any fixes?

Most of the comments in the link you provided mentioned a conflict with Skype, which has now been fixed. I don't have Skype so I read on. I found this interesting comment:

I am a developer of an Excel Add-In product. Some of my customers complained vociferously about the "Cannot Empty Clipboard" box. My product does thousands of cell copies, so the appearance of this dialog thousands of times is quite a hindrance. In the case of my corporate customers, having Outlook open seemed to be what precipitated the problem.
As a paid member of Microsoft Developer Network (MSDN), I opened a ticket on this issue. The engineers of the Visual Studio Office Developer Support Team reproduced the problem with the aid of a small application I sent them.
They explained that Outlook needs to monitor the Windows clipboard. The Paste button or icon needs to be enabled when there is something to paste in a message, so Outlook must constantly monitor the clipboard. Then Excel asks too. Two applications asking for the clipboard contents result in the dumb "Cannot Empty Clipboard" dialog.
The appearance of this dialog is clearly an architectural defect in Windows/Office clipboard management, and the MSDN team acknowledged this. They did not have a solution, and they promised to escalate this issue of MS Office development.
In the case of my program, I have the workaround of programmatically disabling warnings when doing copy/paste.

I closed Outlook and the problem disappeared. Apparently the problem is an Excel problem because Excel empties the clipboard after each use where the other programs don't.

However, I find it disturbing that I have to disable my email in order to drag contents from one cell to another. I also find it more annoying that in the hear and a half since this post, Microsoft has not attempted to fix the problem.

I grab a cell and drag the contents to another location. About 2/3 of the time I get the message I mentioned, and I have to acknowledge the dialog box to continue. But when I close Outlook, as I just experimented with, it doesn't happen at all. I guess "semi-fixed" is a good description because it appears that I will have to give up my email in order to work on my spreadsheets.

It happens on every spreadsheet. Thanks for your interest.

I do not get the message when I use the control keys or when I used copy and paste by right-clicking.

Richard
That was a good thought but, no, the current spreadsheet I created myself and has never been attached to an email.

General comment
I am new to this forum, and at this point I have more questions for people than answers. I am very appreciative for the sincere offer to help with this problem.

I have Microsoft Office Home and Student, version 14, 32 bit
I also have Windows 7 64 bit.

Yes, I do have an add-on in Outlook. Nuance PDF Converter.

Maybe you're on to something. I disabled the Nuance add-in and also the One Note which I have no use for. I am still experiencing the problem. I checked my add-in list and was surprised to see the following active add-ins:

Microsoft Outlook Hotmail Connector
McAfee
Windows Search Email Indexer
Microsoft Exchange Unified Messaging
Microsoft Office SharePoint Server Colleague Import
Microsoft Outlook Mobile Service

I know nothing about these and would be afraid to disable them.

I disabled every one of them. No change.
