Hi
This is a copied reply of Tom Ogilvy's to a similar problem - hope he doesn't mind!
"Hopefully it is just an errant reference which was inhereted from the
configuration you used when you built the file. If so, they just need to go
to the VBE (alt-F11) then in the menu go to Tools=References. Any item
which is checked and shown as MISSING should be unchecked. If it is not
needed, this should clear up the problem. If not, then it should show you
what necessary items are not available and you can go about creating
references to them.

HTH,
Tom Ogilvy

PS - if there were unnecessary items causing the problem, go to your
original file and uncheck these items on your machine. Then make a change
on the worksheet or in your code and save the file (sometimes unchecking an
unnecessary reference is not a change that is detected)."

regards
Paul

The error occurs when they open the file and try to click the Unhide
