Here is an odd one.
One of our users has to resize some of the columns of the same Excel spreadsheet every time he opens it.
This spreadsheet is updated by one person in our Planning department. The rest of the company has read only writes to it. When I open this spreadsheet the layout is fine. The person updating the spreadsheet has got all the columns formatted and sized OK. However when this one user (there could be others that haven't said anything) opens the spreadsheet several of the columns are sized too small to see the information and he has to resize them.
From what I can tell are all running the same operating system and the same version of Office 2003.
