I tried with this script (is a bit shorter, lazy moi :-) and it worked 
fine...
Everytime and with a fast response!

OK, "monkey-clicking" may drop one "mouseup" or two, but in general no 
probs..

on mouseUp
   if the optionKey is "down" then
     put empty into fld  "theWord"
   else
     delete char -1 of fld  "theWord"
   end if
end mouseUp
