In my Flash movie, when the user moves the mouse the alpha of a movie clip changes. At the same time I have changed the mouse cursor. The problem is that when the the alpha is being adjusted the cursor movements get really choppy. Here’s the code that I have on the movie’s first frame:  
function cursorUpdate () {  
\_root.cursor.\_x = \_xmouse;  
\_root.cursor.\_y = \_ymouse;  
updateAfterEvent(mouseMove);  
}

And here’s the code on the cursor MC:  
onClipEvent (load) {  
Mouse.hide();  
this.swapDepths(100);  
}  
onClipEvent (mouseMove) {  
\_root.cursorUpdate();  
}

If anyone’s got any suggestions, do tell! Thanks.
