That's pretty much what I came up with too... Perhaps it's best to just use a browse. The grid isn't used for editing anyway.

The ultimate objective is to refresh other controls on the form based upon the presence or absence of a value in column4 of each row. The only reliable way I've found to do that is using AfterRowColChange. (Wish I had a dollar for every time I've needed a grid.lostfocus method!) However, AfterRowColChange doesn't execute if the user clicks in columns 1, 2 or 3. That's why I was trying to restrict them to column 4...
