Hello,

A coworker of mine opened a spreadsheet. She then clicked on a tab to open
another spreadsheet but that spreadsheet opened in a smaller window and does
not allow her to do anything and she can't close it unless she closes the
main spreadsheet. What did she do? When it is opened, there are no toolbars,
file menu, edit menu and so on and none of them will open when this smaller
spreadsheet is up.

How does she fix it??

Thanks!!!
