This has me stumped, so any help will be deeply appreciated!

I built a form that creates a custom toolbar when the file opens to allow
the user to run macros. Recently several new users have reported a series of
errors when they click any of the custom buttons. I can't reproduce it on my
computer but the errors sound like the buttons are trying to run the macros
from a different workbook that doesn't exist. The users are prompted to
"Enable Macros" a second time and then get a message that the macro can't be
found. The users can, however, run the macro directly from the menu options,
just not from the custom buttons.

When I open the Assign Macro box, I see the current file name as a path in
front of the macro name. Could that be causing the problem? I remember,
sometime in the past, seeing only the macro name (no file name) in the Assign
Macro box.

I've used either Excel 2003 or Excel 2002 to edit the file, depending on
which office I'm working in. I've tried setting the macro assignment to
"This Workbook only", but the file name is still there. On my computer(s),
the file name does change when I rename the file, so the buttons still find
the right macro to run.

I haven't pinned down a common attribute for the all users who have this
error, but several work on US Government sites which have many security
restrictions on software. Is it possible that network security is affecting
the connection between the button and the macro?

Any ideas?

Thanks,
