ScrollablePopUpMenuButton in Flex 4

[GoogleCodeExporter]

I had the ScrollablePopUpMenuButton working fine in my Flex 3 application.
 In the process of converting it to Flex 4 I'm getting this ...

Error: Error #1502: A script has executed for longer than the default
timeout period of 15 seconds.

If I switch to the normal PopupMenuButton that comes with Flex 4 the error
goes away.
