I have been using apple work 5.03 long time.Yesterday I had to
use equation editor.When I cliked on the sum up symbol,it
says "equation editor
can not be found.So ,I thought it hasn't been installed.I've re-
installed apple work but I've got exactly the same message.The weird
thing is,I can run the equation editor by itself.But How can I call
it in applework when I click on the symbol.

thanks
Kelly
