Program working under on login, not another.

I have a legacy FFW  2.6 program running under terminal services    The customer complains that a certain report "hangs" and never completes.   I test it on my login, everything is fine.   I have them create another login for me using their profile, that works fine.   The permissions and setups should all be identical.   I have them log  into using my login, and it works fine.    They have the same default printers.   They have the same exact work space and local disk I have no idea what there is left to try.
