Can't copy outside of Excel 2007 after copying within a spreadshee
 

I do a lot of copy and paste from Excel to external files/applications and
vice versa. In Excel 2003, I could copy a value in a spreadsheet, paste it
into an external tool or file and run a search or process, copy the results
from the external process, then paste back into Excel. However, since moving
to 2007 I can no longer to do this. I am able to copy the value in Excel and
paste it externally, but when I try to copy an external value and paste it
back into Excel, the value that I copied in Excel is pasted instead. It's
basically ignoring the information that I copy outside of Excel until I've
pressed the "Enter" key in Excel to release the copy mode. Has anyone else
experienced this issue?
