In 'landscape', the keyboard takes up the whole screen and you can not see what's underneath.
You are getting what is called Extract Mode when your screen is in landscape mode. I ran into the same problem and, after questioning Google, found this was intended behavior on the assumption that there would not be enough space to display anything useful. Even the entry field is not your entry field. To get around this problem, do the following:
Under Sub Globals, define:
Dim Ref As Reflector
and under Activity_Create:
Ref.Target = TextEdit ' The text field being referenced
Ref.RunMethod2("setImeOptions", 268435456, "java.lang.int") 'IME_FLAG_NO_EXTRACT_UI
That should give you back your normal screen in landscape mode.
Of course you will still have to deal with handling the appropriate layout in landscape mode.
