I am not sure how this happened, but everytime I open a particular workbook,
it simultaneously opens another one. The workbook file that I want to open
is named PARD , but the two that open up are PARD:1 and PARD:2 .
Everything I do in one is mirrored in the other; it doesn't matter which one
I work in. There are no links present, and when I looked under the shared
workbook status, I am the only one using it. How do make this stop happening?
