I have a workbook that is shared on the network. The users all have the same
rights to the folder where the book is kept.

The problem is this:

User A does her entries, has hidden several rows so that they do not show up
on the print out. She saves the file and asks User B to do her entries.

User B opens the workbook, but some of the rows that were hidden are now
displayed on the screen. If user B does her entries saves and User A opens
the file, User A is complaining that User unhid the rows.

What is causing this problem??

Please advise.
