It is likely not actually 3 or 4 separate instances of Excel. Excel is
probably configured to show each workbook in the taskbar. Go to the Tools
menu, choose Options, then View. There, uncheck the "Show windows in
taskbar" setting.

I have a user at work who is having a problem when he opens certain excel
workbooks, that contains multiple worksheets. Several (3 or 4) instances
of this workbook open automatically, each with a diffirent sheet open.

Has anyone seen this and know what the fix is?
