I have a user who reported this, and we have verified the behavior on
different computers. She has a spreadsheet with 10,000 rows and about 50
columns. When she highlights the whole spreadsheet, and selects Format
cells, wrap text ,the cpu levels rise to 100% in Excel 2007 and the process
takes about 5 minutes before it returns to normal. The user perception is
that the system is locked up. With Excel 2002, she was not having the same
experience. The process took about 20 seconds to complete. We duplicated
this behavior on two test computers. Is there anything that can be done to
fix this?

She has a P4 3.0 ghz system with 1gb RAM and an 80 gb hard drive.
