Office '07: Shared document will not save

[AquaSabes]

Hello,



First post, thanks in advance for assistance.

I'm trying to help a user with an Excel 2007 problem. They have an Excel 2007 document shared on the network and all indications are that the document is shared and allows simultaneous changes.

One of the users is not able to make changes and save it. When she presses save, she gets a pop up indicating that the document is read only and wants her to 'save as'.

I haven't seen this before.

Any suggestions are greatly appreciated. Thanks!
