[comp.sys.mac.hypercard] HELP! How do you change the cursor while over a button?

I'm trying to implement a hypertext help function in HC 2.0 and I can't get
it to work.  I want the cursor to change anytime it goes over a button 
which has help available about it.  I've tried the following handler with
no success.

on mouseEnter
  repeat until mouseLeave is true
    set the cursor to plus
  end repeat
  set the cursor to hand
end mouseEnter

Why doesn't this work?  I've tried other variations with mouseWithin with 
a similar result. Anybody gotten something like this to work?  Thanks
in advance.
