if you want the cursor to be persistent after the script is finished,
you have to  set the lockcursor to true.

The above is the "normal" behaviour.

The cursor is reset after the script is finished.

on mouseWithin
    set the lockcursor to true
   set cursor to arrow
end mouseWithin

I would advice to script a mouseenter-handler:

on mouseenter
    set the lockcursor to true
   set cursor to arrow
end mouseenter

And don't forget to set the cursor back on mouseleave...
Or the cursor will stay forever (or until you set it again) even in the
development-environment, which is really annoying...

on mouseleave
   set the lockcursor to false
   set the cursor to hand ## or whatever
end mouseleave

Hope that helps.
