thanks derek!
just the sort of nastiness i was hoping for.
i didn't go down the prototype line of attack as i have built up distrust in
getTextExtent
the text would potentially get styled and other elements within the same
component as the textField depend highly on the correct text width being
returned, or textField width being set in this case.
but there does not seem to be a way around using getTextExtent, so i'll play
around and let you know what happens.
muach appreciated!
