[COLOR=DarkGreen]Hi guys, i have little problem and hope someone can help me out… So ive attached a drop shadow filter to a mc… but when i roll out of it i want to remove the filter effect… ive searched livedocs and found document.removeFilter(), but i dont really understand how it works =( so here´s my code:[/COLOR]

import flash.filters.DropShadowFilter;  
var myDropFilter:DropShadowFilter = new DropShadowFilter(35, 90, 0x9A9A9A, 5, 30, 30, 1, 50, false, false, false);  
[COLOR=DarkGreen]  
This function is added to several MC:S with a loop the result that it slows down everything  
[/COLOR]target\_mc.onRollOver = function() {  
var myFilters:Array = target\_mc.filters;  
myFilters.push(myDropFilter);  
target\_mc.filters = myFilters;  
};  
[COLOR=DarkGreen]When i roll over it several times it just adds one more drop shadow object to the instance, but i suppose i can control that with some function, i will look into that next… Help please [/COLOR]
