Actually, I'm not explicitly opening a window (should I?), I just call 
newterm(). And come to think of it, I don't know if the code clears the 
line *after* my form field; what I did notice was that it erased my 
"label" in *front* of the field. Therefore, I assumed it was clearing 
the entire line.
