I've checked the value of one my TIB_Edits on the same form and it
has the correct row's value when this event occurs (I read it via
IB_Edit4->Field->AsString, is this OK?), so I think it's just the
TIB_CheckBox that is a bit slow.

Can do! (You mean something like (ClientsQry->FieldByName
("ACCNTHLDR")->AsString == "T"), right?)

I'm not sure what you're suggesting here. Can you elaborate please?
