MovieClip Filter Causing issues with EventListeners (mouseEvent.ROLL_OVER)

Question

Hello,
I have been working on a flash photo gallery for the web. It loads thumbnails from an xml file into a loader which is then made the child of a movieclip.
The thumbnails are animated and triggered with mouse events of ROLL_OVER and ROLL_OFF. I have this working, or appearing to, when the movieclip containing the loaded thumbnail has no filters applied to it.
I want add a drop shadow on the ROLL_OVER event and remove the drop shadow on the ROLL_OFF event. I also have this working, however my problem arises when I mouse over the very edge of the movieclip. This cauese the ROLL_OVER and ROLL_OFF function to fire in rapid succession, creating a flashing dropshadow. This looks aweful and I really have no idea what would be causing this issue.
Thanks in advance for any advice!
Regards.

Thanks for the reply.
I also found it difficult to believe that the filter was causing issues with the roll over/out events. I will expand on the example code you provided so you get an idea of what I am trying to accomplish and where my issues arise.
EDIT: I should add that the issue is only present when I tween AND add a filter. If I only add a filter or if I only tween I have no issues but the combination or adding a filter and tweening causes the OVER/OUT events to fire rapidly.
//This code does not result in a flashing animation
myClip.addEventListener(MouseEvent.ROLL_OVER, overClip);
myClip.addEventListener(MouseEvent.ROLL_OUT, outClip);
function overClip(e:MouseEvent):void
   myTween =  new Tween(myClip, "scaleX", Regular.easeOut, myClip.scaleX, 1.5 , 3, true);
   myTween =  new Tween(myClip, "scaleY", Regular.easeOut, myClip.scaleY, 1.5 , 3, true);
function outClip(e:MouseEvent):void
   myTween =  new Tween(myClip, "scaleX", Regular.easeOut, myClip.scaleX, 1 , 3, true);
   myTween =  new Tween(myClip, "scaleY", Regular.easeOut, myClip.scaleY, 1 , 3, true);
//However if i add these lines of code to add and remove a filter I can observe the flashing effect when the mouse is near the edge of the moveclip
myClip.addEventListener(MouseEvent.ROLL_OVER, overClip);
myClip.addEventListener(MouseEvent.ROLL_OUT, outClip);
function overClip(e:MouseEvent):void
   myClip.filters = [myDropShadowFilter];
   myTween =  new Tween(myClip, "scaleX", Regular.easeOut, myClip.scaleX, 1.5 , 3, true);
   myTween =  new Tween(myClip, "scaleY", Regular.easeOut, myClip.scaleY, 1.5 , 3, true);
function outClip(e:MouseEvent):void
   myClip.filters = [];
   myTween =  new Tween(myClip, "scaleX", Regular.easeOut, myClip.scaleX, 1 , 3, true);
   myTween =  new Tween(myClip, "scaleY", Regular.easeOut, myClip.scaleY, 1 , 3, true);
Is there something obviously wrong with this approach to adding a filter/tweening? I am fairly new to flash.
Thanks again!
