Excel 5.0 unexpectedly quits all the time. Recently it has been corrupting older files too. This never happened before I upgraded to OS 9, does anyone else have this problem?, should I just upgrade to excel 98?

I tried everything and eventually had to put my hand in my pocket.

Even MacUser UK could not offer any meaningful advice, and as for Microsoft...

More bucks to Bill I'm afraid!

Excel 5.0 is not considered Y2K compliant by Microsoft, anyway. If you want it to work properly after Jan 1, you should probably upgrade anyway.

I spoke with Microsoft Tech Support. There is a compatiblity issue with Mac OS9 and Excel 5.
It looks like I'll be upgrading to Office 98.

I have the same problem and have come across this Tech note from MS - http://support.microsoft.com/support.../Q257/5/46.ASP , sorry!
OS9 and MS Excel 5 are not a happening thing and yes, Excel MUST be upgraded...
