I am doing this already.. here, I wrote a two screen example of this
problem.. in the constructor, I've created Main and Main2 .. main has a
label that says "this is form 1" and a push button.. main2 has a label
that says "this is form 2" in a different place than the label on Main and
another push button in a different place than the other button... Both are
set to visible, but not checked for Modal or Save Behind.. Then this source
to flip back and forth between the two screens... What happens is that when
Main 2 appears, Main's controls are still visible.. curiously, when you
click Main 2's button, Main appears normally. This only happens on OS3.5 ..
this code flips back and forth clearing the screen as expected on all
pre-OS3.5 versions I've tested (PalmPilot Pro, OS 3.0, OS 3.3)
