Change the Cursor?

[Magnus von Brömsen]

Hi

I'm trying to change the cursor. In an image I have this script:

on mouseEnter
   set the cursor to cross
end mouseEnter

But nothing happend. When I switch to the Browse-tool for testing, the 
cursor is always the little "pointing finger" (except when over editable 
textfields).

I want to have some kind of signal to the user ("Click here"). Any other 
ideas?
