With reference to the first post in this thread: What I didn't mention
in the description of the situation, because I had no Idea it was
significant, is that the two text boxes - StartDate and StartTime - are
inside of a frame, aka group box. This makes all the difference in the
world. If I change the tab order of the two text boxes, the StartTime
one will update on exit and the StartDate one won't. However, in either
situation, exiting whichever textbox won't update correctly in the
opposite direction, that is, with a shift+tab, will update it. So now
does anyone have a solution to this?
