Well I fell foul of using form props in SQL years ago and always assign them to a var in such.

It just so happens that I suspected similar here and had already assigned it to a var and tried that, to no avail. It seems my problems stem from having that Days_Op as part of the copmposite key on which the table was ordered, as I explained. Although I can't see why the file ptr should have moved, when I hadn't changed the value of Days_Op. I have no access methods on the prop. so no side-effects as you pointed out. Besides, in debug I would have caught that happening.

Thanks Mate

If an access method fires a thisform.refresh and the refresh of some control does a GO BOTTOM... This just sounds terribly risky to me.

I first noticed that after I'd set some look-up FKs from listboxes, on the INFOBASE rec (textbox shows the key and listbox shows the look-up text name), and saved, the values disappeared from the record. These are chronological journey records pertaining to a parent ROUTE. There may be many of them for each Route, all maybe practically identical save for their start and end times, so I'd not noticed the rec changing in the past (if it did).
