I got it...
When I put in AfterRowColChange of the grid:
THIS.Column2.Enabled = table.logical

there was some quircky behavior, it 'almost' worked.
But I then added to the BeforeRowColChange:
THIS.Column2.Enabled = .T.

So I am re-enabling the column as leaving the cell, and then re-checking to see if I need to enable or disable in the AfterRowColChange. Works like a charm.
Thanks for your help!
Kevin
