>I'd like to be able to drag a row from a grid on one form and drop it onto a grid on another form, and have it appear as a new row in the target grid. From browsing the MSKB it appears doable, though non-trivial.

I don't see why not, I've never done it, but why are you hesitant? Just drag+drop, then copy the record from the source table, the delete it there.
