Excel corrupts when asking to update vlookups

[Bob-ISTA]

We are experiencing weird behavior with some Office 2K3 Excel spreadsheets
that contain lots of calculations, but no macros. On some pc’s Excel acts
normally, on others you get the error. I have a couple of screen shots
available.

Any help is appreciated.

If desired, send your file to my address below. I will only look if:
1. You send a copy of this message on an inserted sheet
2. You give me the newsgroup and the subject line
3. You send a clear explanation of what you want
4. You send before/after examples and expected results.
