Somehow I created a duplicate spreadsheet, but can't delete it without
deleting the original. They open and close simultaneously. I simply want to
eliminate the :2 version. It's annoying and confusing to anyone that doesn't
realize what they may be looking at. Honestly don't know how I even created
it.

When I open 'file Name.xls' it opens both 'file Name:1.xls' and 'file
Name:2.xls'.

Thanks!
