But that is incorrect. I do not have Rosetta installed.
All I know is that Excel 2004 is very unpredictable running on system 10.6.1. Others have reported problems with multiple MS Office 2004 applications. You might want to try 10.6.2 that should be available for download fairly soon and see if it cures any of your problems. If that doesn't do it, I still recommend Excel 2008, but if you're determined to stick with 2004, try installing Rosetta. Maybe it will help. Maybe it won't. I think your main problem is that the Mac OS X Snow Leopard is leaving 2004 behind. When I upgraded to 2008, all of my former problems went away and I've never had such a smooth, quick operating system experience.
