>>>Well it did, the row still got selected, BUT the ARCC wasn't firing. Put grid.AllowCellSelection back to .t. and set it .readonly=.t. instead. And it just started working, magically.

It was exactly the grid.AllowCellSelection=.f. that caused the snafu - because the call to parent.refresh() refresh was in the AfterRowColChange, and it wasn't firing. Confused me endlessly. I probably doubleclicked it in the PEM window while thinking the mouse pointer was elsewhere, so no amount of backtracking over what I did would fix this, because I absolutely don't remember doing it.

Also the behavior, where the controls wouldn't refresh until I clicked them, was so familiar and none of the deja vus were helping, as the only conclusion was "it didn't refresh" - but then why didn't it? Aaah... so glad I found it. I can now go back to being normal nuts, not this extreme degree.
