>It sounds like just some extra housekeeping that the grid is doing. From the grid's point of view, it doesn't know where your going after you leave it, or what your going to do (like move the record pointer). This being the case, the best bet would be to fire any code that would prevent the move in the Valid, then if it's Ok to move, fire any housekeeping code that might be in the BeforeRowColChange.

No, you're no worse than the vfp developers :) The problem with the Valid here is that it's no longer usable for everything (e.g., setfocus), and the grid has no Lostfocus to use instead...anyway, now that I've traced the problem to the Beforerowcolchange firing late, I can deal with it easily enough. Just caught me by surprise...
