Okay..here is a weird one

I have a textbox which is bound to a dataset and a leave event which changes
the textbox.text value. The problem is it is changing in the debugger but
goes back to original value on the form???!! Any ideas?
I think it may be changing the value (I see if flash by) but when it gets
to next field the original value is back! I checked and I don't see any other
events for this textbox. BTW, how can I continue to single step thru code
after end sub on event? If I couls do this I might get a clue what is going
