Hi

This isn't a bug so much as a change of concept when using a Combo.  The Combo
is a combination of an EditText and a List.  So when you want to get the text
from the EditText you need to ask what its control id is.

ie (in your onChange)

     setText(EditText4,getText(getEdit(Combo5)))

getEdit() is described (in the documentation I have, also 0.60.6) in the
"Controls" section.  It isn't mentioned anywhere in the "List Control" section
though, so I can understand the confusion.
