you may have a workbook in excel's start-up folder. Does the VBA call a
function/sub from another workbook?

Using Excel 2007. I got this annoying problem from time to time, that when
I open a particular workbook, Excel also opens another (also particular)
workbook. The first workbook has a lot of VBA code in it, but I don't see
anything in the Auto_Open() procedure that could cause another workbook to
open. What could cause this and what do you do about it?
