I have a 2003 Excel workbook that won't open, exactly. When you open it the user is asked about enabling macros and the choice to update the links is offered but it's not there. If you click on the Window button in the task bar it doesn't show it. In the network system where we use the workbook, if you try to open it again on a different computer you get a message telling you that it's already open and you have the choice of Read Only, Notify, etc. If you click Read Only it doesn't come up either but supposedly it's open on the other computer that didn't show it. For business reasons I cannot attach the file.
