select tool problem

[Mr X]

Aich!

I couldn't figure this one...

How do you detect a mouseenter or mouseleave message
in an image object if you've choosen the select tool?

script of img 1 
on mouseenter 
  choose select tool
end mouseenter

on mouseleave
  choose browse tool
end mouseleave

Corollary: if a button "works" in a separate palette,
how can you use the select tool in an image in a 
palette stack?

If anyone s'got an answer, thanks in advance!

cheers
