I have a spreadsheet with approximately 12,000 entries. All entries are
hyperlinked to .pdf files. Every time I check the spreadsheet, there will be
anywhere from 5-10 hyperlinks that don't work. Either the hyperlink LOOKS
like it's there, but when you click on it, you get "requested filed does not
exist" or it looks like it's there, but there's no response when you click on
it.

Right clicking when the first scenario happens will bring up the shortcut
menu that includes options to edit hyperlink, remove hyperlink or insert
hyperlink. The 2nd scenario brings up the shortcut menu with only "insert
hyperlink."

Does anybody have any ideas what might be happening? The worksheet is used
by multiple city/county entities.

Thank you.
