"There's a problem with the clipboard" error

I'm getting the "there's a problem with the clipboard, but you can still paste this content within this workbook " popup error. I copy and paste up to 10,000 entries to an external program using macros. I have reinstalled and tried every fix I've seen on the web. I simply cannot use excel with this error. I have had to switch over Open Office for copy and paste, but all my macros are in excel. It's really a pain to go back and forth between 2 programs.

I have level 2 Excel support calling me tomorrow about this, and level 1 today had less knowledge than me on the matter.

Anyone have any help or suggestions?

Thanks
