Special paste not working - even with all browsers closed

Hi there,

I have excel 2007, and I am unable to use special paste. It still doesn't work when I close all internet browsers, and I don't have skype on my computer, so I don't think it's a add-on issue. I am trying to copy and paste (including formatting) from one excel spreadsheet to another. I have repaired excel, entered excel safe mode, and in excel options, "show paste options" is checked.

What am I doing wrong????

TIA
