We have a user trying to open an Excel spreadsheet (.xls) in Office 2007. Excel opens and you can see the selected cell in the Name Box and the cell value in the Formula Bar, but the spreadsheet is not visible. If you type a different cell in the Name Box it changes and updates the value in the formula bar so it appears that the file is operational but just not visible.
This spreadsheet can be opened on many other computers in the network, and this computer can open all other spreadsheets. It seems like some sort of Excel setting / issue but I don't know what to check. The spreadsheet is not using macros (but they are enabled anyway).
