listener are not rendered until the next frame refresh, which is determined by the frame rate

of the movie. Unfortunately, in Flash 6, updateAfterEvent() cannot be used to force a

screen refresh from within an onMouseMove() listener; updateAfterEvent() has an effect

only when invoked either from a movie clip mouse or key event or a setInterval() callback.

Hence, in Flash 6, it’s often appropriate to create a movie clip simply to implement

onMouseMove() with a screen refresh. For example:

// Create the movie clip

this.createEmptyMovieClip("mouseListener_mc", 1);

// Assign a callback function to the clip's onMouseMove handler

mouseListener_mc.onMouseMove = function () {

// Respond to mouse movement (details omitted)...then refresh screen

updateAfterEvent();

}

See the Example under Mouse.hide() for custom pointer code. Mouse trailer code is avail-

able at the online Code Depot, in varying degrees of complexity.
