Yes, that would work, and I don't think it would be any less stable
than having two separate versions (if you do it right :-) From your
description, it sounds like version 2 is a superset of version 1. If
that is true, then you won't even need the #ifdef VERSION_1. Simply
make the button unusable in Constructor or your PilRC source file,
whichever you are using. Then for VERSION_2 make it usable with
FrmShowObject.
This one conditional should be all it takes to make your app work. If
you want to reduce the size of the VERSION_1 app, you could wrap the
VERSION_2 button event handling and the form handler in conditionals.
Also, a button that is unusable will never generate a ctlSelect event,
and thus there will be nothing to ignore.
