Can't copy/paste in the same workbook

[DJM1216]

Hello, I have a workbook with multiple tabs. I'm trying to copy some data from one tab to the next. Walking through the steps:

I highlight the data I want to copy.
Right click "Copy"
Go to the tab where I want to paste
Right click (and "paste" is grayed out)

This is all within the same workbook. Any ideas?

Well, this didn't work for me. I have still the same problems. When I try to cut (or copy and paste) I see this message:
"Excel cannot complete this task with available resources. choose less data or close other applications"
I have no other applications open and this only happens in this workbook. Somehow and suddenly the workbook is messed up. I have been accued of changing things randomly but I don't think so this time
I am using Office 2010 on Win7 with 2GB ram
