I have a strange problem at one of my customers.

If User A opens a spreadsheet and starts editing it, then User B opens the same spreadsheet, he does not receive the "This Speadsheet it open, Read Only" message; he is allowed to edit away at will. The only time he gets a message is when he comes to save, at which time the system then prompts him to save a copy instead.

Any ideas out there??

Regards

Paul.
