Excessive CPU/memory use

M

Mike Lints

I have a problem running Excel 2007 on a laptop with Windows Vista. Any time
I work with a file of any substantial size, the program repeatedly freezes
up. Windows Task Manager shows that Excel is using all the available CPU,
even though I'm not performing any tasks. This may go on for 2-3 minutes or
more, then I have a few seconds to try and do some work in the file before it
freezes up again for another 2-3 minutes.

The file I'm working on has about 15 sheets of 10,000 records each with
about 25 columns per record. The file size is about 40 MB, but Task Manager
reports that Excel is using around 400 MB of memory.

Can anyone tell me why Excel is using so much memory, and more importantly,
how I can prevent it from repeatedly interrupting my work while it seemingly
performs some task(s) in the background that uses all the CPU?

Office 2007? That means you're looking for the windows group at
