I have 3 workbooks: WB1, WB2, and WB3. WB1 and WB2 are both linked to WB3 but
not each other.

WB1 contains volumes and WB2 contains costs. When I open these two together
and say no to updating the values change anyway.

Any clue on why two workbooks update even if I say no or don't want to have
WB3 open?
