Text fields are focused onmousedown (try this -- click and hold, and note that
the textfield gets focus).  Cancelling the onmousedown event should indeed
prevent its default action (that of focusing the textfield).

dup of bug #144503? it also talks about "onmousedown".

(From bug 144503: note IE and Nav4 do allow focus on the textfield in this case.
Mozilla is standards correct but real-world incompatible.)
