Hello-
Hopefully you have the matter resolved by now, but if not here are some
thoughts:
1) Is the acct having trouble or are you unable to open & edit the
copy? If the latter, make sure the original is not still open when you
open the copy.
2) After you quit Excel, select the copy, use Cmd+i and see if the file
is "Locked" in the Get Info window. If so, uncheck the checkbox.
3) Have you tried using the Save As command to save a copy fo the file
directly to the target disk?
4) Is the XL Mac file format one that can be used by whatever version
of XL your accountant has? If your file is in a "newer" version his may
be able to open but not edit the file. Again, Save As may be the
answer... change the File Type in the listbox below the file name
field.
More specifics would be most helpful|:>)
