components and mouse pointer change

[weezil webforumsuser@macromedia.com]

I'm developing a component in which there are clickable areas and I can access button type events by doing something like:

componentClass.prototype.onRollover = function ()
{
trace ("I've been rolled over!");
}

But when you rollover, the cursor doesn't change to indicate that it's clickable. Is there something I can put in here to make the cursor change from a 'pointer' to a 'hand' to indicate I can press it!? I've tried just dumping an invisible button on the component stage, but it don't appear to be activated withing a component!
