I posted my solution to Stack Overflow just a few minutes after Raju
posted his:

Here is my solution using delegates with the application Idle event:
<canvas width="1000" height="665" debug="true">
<view id="v" bgcolor="0xcccccc" width="200" height="200">
<!--- @param boolean mouseisover: true when the mouse is over -->
<attribute name="mouseisover" type="boolean" value="false" />
<!--- @keywords private -->
<!--- @param lz.Delegate dlgt_repeat: stores the lz.Delegate object -->
<attribute name="dlgt_repeat" type="expression" />
<!--
Called when the 'onmouseover' event occurs
-->
<handler name="onmouseover">
// Step 1) unregister any existing delegate
// mark it for garbage collection
// and prevent its event from triggering:
if (this['dlgt_repeat'])
this.dlgt_repeat.unregisterAll();
// Step 2) update this.mouseisover flag:
if (!this.mouseisover)
this.setAttribute('mouseisover', true);
// Step 3) create an event Delegate and call it
// on the next application idle event:
var objDlgt = new lz.Delegate(this, 'doSomething');
this.setAttribute('dlgt_repeat', objDlgt);
lz.Idle.callOnIdle(this.dlgt_repeat);
</handler>
<!--
Called when the 'onmouseout' event occurs
-->
<handler name="onmouseout">
// Step 1) unregister any existing delegate
// mark it for garbage collection
// and prevent its event from triggering:
if (this['dlgt_repeat'])
this.dlgt_repeat.unregisterAll();
// Step 2) Update this.mouseisover flag:
if (this.mouseisover)
this.setAttribute('mouseisover', false);
</handler>
<!--- @keywords private -->
<!---
@param ??? objDummy: required for SWF9+ run-times due to
AS3 (ActionScript3 compiler requirements)
-->
<method name="doSomething" args="objDummy=null">
<![CDATA[
// Note: CDATA allows '&&' to be used in script below,
// alternatively omit CDATA and use '&&' instead
// of '&&'
// Step 1) Execute your code you want to run here:
if ($debug) Debug.debug('Do something...');
// Step 2): If mouse is still over and the event
// delegate exists then schedule the event to be
// executed upon the next application idle state:
if (this.mouseisover && this['dlgt_repeat'] != null)
lz.Idle.callOnIdle(this.dlgt_repeat);
]]>
</method>
<text text="Move mouse over" />
</view>
</canvas>

Is it possible to do something like this
while (view.mouseover == true) {
preform action
}
I want to have an action repeat for as long as the mouse is over a
specific view.
