Toolbar icons freeze/stop responding

[tristanh]

I am running Excel 2003 with SP1.

At random intervals, Excel's toolbar icons stop responding!

You move the cursor over them but they can't be clicked. I have to exit Excel every time to get back to a normal state. I have re-installed my computer and installed office 2003 again but keep getting same issues.

Anyone experienced the same issue?

I am running: Conditional sums

or Multiple conditional sums

Is there anyone else that's experienced this issue recently?
