I have a problem that is constantly repeated. In one file, there are several buttons that are assigned with certain macro procedures. When I send the file to the user to enter data, it returns with a terminated assignement between macros and buttons in all sheets. VBA code is ok, just connection between buttons and macros was broken. The problem happens only with one user, all other users are returning the correct files.
The file is protected at all time and the user can not unlock it.
If anyone knows what the problem is, please give me a hint.
Thanks in advance.
