yeah, sorry. It's highly possible that I'm confused (it happens )
but for example -->
//you have your imagecontainer or whatever, add a boolean and some listeners..
something like that maybe, I'm just going off the top of my head here and trying to help out is all.
var currentlyHovering:Boolean = false;
currentlyHovering = true;
currentlyHovering = false;
//and you can have an enter frame event on the app...
//do your thing and call your perpetual hover code
Again, all apologies if I'm not fully understanding what you're trying to do.
