Heh; this works, but careful readers may wonder why, since the print  
function uses t.value, not tarea.value. Turns out Firefox emulates an  
IE DOM quirk, only if the name lookup would fail, where elements  
given ids (or names? I forget) reflect as global properties.  Sick,  
but we found too many pages counting on it without detecting non-IE  
user agent.
