I have looked into implementing Mark's solution,
but it breaks a lot in my current implementation
because I already use FrmHideObject/FrmShowObject
to control if my fields show or hide...
If there are other solutions I would very much like
to hear about them. Oh, I forgot to mention that my
program must run on PalmOS < 3.5, so no WinScreenLock()
if that could have solved my problem...
Thank you very much in advance!

Would it not be more efficient to hide the form instead of each field, do
updates, then show form? Is this allowable?
