It looks like excel tries to help by remembering the last thing you used.
So maybe you could have a dummy workbook that you put in your XLStart folder
that does a Find with the settings you like:
Option Explicit
Sub auto_open()
Worksheets("sheet1").Cells.Find What:="", After:=ActiveCell, _
LookIn:=xlValues, _
LookAt:=xlPart, SearchOrder:=xlByRows, _
SearchDirection:=xlNext, MatchCase:=False
ThisWorkbook.Close savechanges:=False
End Sub
The workbook opens, does a find (to fix your settings) and then closes to get
out of the way.
