Activates the Previous Window (higher in Window list or cycles to bottom of List):
Return to List
ActiveWindow.Previous.Activate
NOTE: A better alternative is to place Window names into variables (such as with "strTemp = ActiveWindow.Caption" -- Then activate the various windows as you need to: Windows(strTemp).Activate -- This way you don't have to worry about the number of open windows!!
