I am noticing a puzzling/vexing behavior which I think has been also vexing others in several forums, but I haven’t seen a relevant reply so far (no solution, nor even confirmation that this is in fact the current behavior, or whether it is the intended behavior): When I first start entering data into a new spreadsheet (usually by typing, and setting Word Wrap on) I enjoy the fact that the Row Height increases and decreases automatically to fit cell contents as I edit. Then, for some reason, I adjust one or more row heights manually or by choosing Optimum in the dialog, then forever after the Automatic Row Height mode is no longer available for those Rows. I see nothing in the Help that tells how to turn on Automatic Row Height again. Is this because that is in fact impossible? If yes, please fix it. If no, please add the instructions to the Help, and reply here.
