Hello…my question is : IF this can be done how do you do it, I’d like to have a picture (like a background pic for instance) change on rollover but i’d like for it to change only in the area where the cursor rolls over not the entire picture changing at one time

Hi,
It can be done with a mask.
On roll over set the mask’s x & y to the x & y of the mouse.
This needs to be in an enterFrame if u want the the mask to move within the button.
this tutorial is about a hover caption, you need to do something similar but with the mask wich is, of course, within the button.

Hope I haven’t made things worse.
Cheers
