We have Link Finder plugin with Excel 2000 to find and delete external
links in excel spreadsheet. It has been working fine. However, with one
of the user, on a specific spreadsheet, the "find links" menu item does
not show up at all. At the same time, when I open a blank spreadsheet
on the same machine, "Find Links" shows up.

Even I tried enabling the find/delete links by going to add-ins, still
no luck, any ideas?
