I could do that. In fact, that's how I was doing it in the old version of 
the program and it worked fine. I even had similar dialogs for both 
updating a row and deleting it. But someone suggested that I avoid using 
extra dialogs to do this kind of thing and just do all of it right in the 
table so I'm trying to do that now. I have update and delete working fine 
but am struggling a bit with insert. 

I may ultimately go back to using an insert dialog - although I think I'll 
leave update and delete so that both are done directly from the table - but 
I'd like to see if I can get the insert to work within the table. But I'm 
having trouble forcing the new cells to be edited in turn.
