This file might also be useful to you. There's a method that'll let you detect a click on an object of any shape (the example I used is a png of a banana).

The attached User Actor will return True if the mouse is within the Rect or False otherwise.

This User Actor will do the same but for a Circle area rather than a Rect.

Hopefully these help.

Another thing you can do is have an image track the mouse position. This way you can show or hide the image as you like. The Image can be a Cursor.. just keep the real cursor hidden.
I like to use Matte ++ as the actor that allows me to move the Cursor around. I find it easiest to use. This tutorial (first half) might help you in setting this up: Digital Chameleon

you can hide the cursor in the preferences and add your own cursor using the "Stage Mouse Watcher" and  the "Shapes" actors

In Isadora is it possible to consider pictures on stage like objects that you can select and detect when you click on them whaterever their position ?

something with eye++ could work:

I have another question please. I have to detect a mouseclick on pictures visible on stage. I have definite areas corresponding to the picture positions and I detect when there is a click inside this area.
