problems selecting a list field

[Björnke von Gierke]

I have several list fields (traversal on, lock text, list behaviour, 
visible, enabled) when the field contains at least one line of text, 
then there is no problem. BUT when there is no line in that field I get 
the following enerving behaviour:

-the field receives no mouse events (enter, leave, up , down...)
-the field gets not selected (selectedObject, selectedField, 
focusedObject...)

I have a button which generates new lines for the field which is 
selected. I am unfortunately unable to make a line when there is none 
in the field... because the field won't get focused (or do anything 
else) when clicked!
the Button can of course not receive the keyboard focus (as that would 
deselect the field)

the behaviour is the same whatever version of RunRev I use.

so how to work around this... glitch ?
