A copy of XL 97 in this office has suddenly developed new behaviour. When
you start it, it opens, but then shuts down after a fraction of a second. It
opens OK in Safe Mode.

I have tried the following with no luck:

1. start XL with the /RegServer switch
2. Untick all the Add-Ins and try to re-start.
3. Move the XLSTART folder to the Desktop.
4. Empty the Recycle bin.

I would appreciate any suggestions.
