Unwanted Automatic Link Update
 

I have two separate worksheets (BID#1 and BID#1REVISED) that are each
separately linked to the same third worksheet (PRICING). The first two are
not linked together at all (the second is a Save As... of the first). If I
open both of these BID worksheets at the same time to compare them, WITHOUT
updating values, the older one automatically updates its linked PRICING
values to match the newer one's linked PRICING values.

what's going on???
anyone? HELP.
