How to disable the hand cursor when it passes over a button
Create your button as you normally would.
Give your button an instance name in the properties panel.
I named mine "blueButton"
Click frame #1 of the timeline that your button is placed
on.
Open your Actions panel (F2)
Enter this ActionScript:
//Sets hand cursor off for your button instance
blueButton.useHandCursor = false;
//Sets hand cursor on for your button instance
greenButton.useHandCursor = true;
