The name of the Excel Workbook disappears from the title bar in excel after saving a non-Vista document.
Excel 2000, 2003, 2007, 2010.
A number of macros are used in Vista reports, amongst others a macro that changes the title bar from displaying "Microsoft Excel - document name" to TAC Vista Reports - document name.
If working in the instance of Excel opened by TAC Vista reports, close the Vista reports macro by selecting Vista Reports\Exit from the menu. Alternatively, opening Excel from the start-menu will also avoid this issue.
