I suppose you could trap all possible events but that feels like chasing 
your tail to me. My gut says it would be fragile.

There's no easy way to do it the way you want. Openfield is where the 
information is.

Can you do the whole redraw on openfield instead of closefield? Store 
the data you need on closefield but do the rearranging on openfield. The 
two messages are back to back, and if you lock the screen on closefield 
there shouldn't be any visual distinction.

That would still fail if the user doesn't actually focus on another 
field though. You could document that they need to hit the Enter key in 
that case, and trap for that.
