Track Changes: Making "All" the default
 

hello:
We are tracking changes on a workbook posted on Sharepoint. Everytime i
check out the doc and view it, i must change the Track Changes default from
"last time I saved" to "All". How do I make "All" the default so that users
do not have to open Track Changes and make this selection (from the "When"
pulldown.)??

Much appreciated,
Bettergains
