>                 Key: XAP-202
>                 URL: http://issues.apache.org/jira/browse/XAP-202
>             Project: XAP
>          Issue Type: Improvement
>          Components: Widgets
>            Reporter: Rob Gagne
>         Attachments: performance_ie.patch

> Provided 3 performance improvements:
> 1. New attribute on AbstractWidgetBridge that specifies whether mouse move/out events are needed; defaults to false and is currently only set by ButtonBridge which is the base for all of the widgets that change style.
> 2. Disconnect mouse move events when entering a component and reconnect them when exiting
> 3. Switch IE to use mouseenter and mouseleave; these don't report leave until actually leaving the component, mouseout reports when leaving a child element
> These 3 changes dramatically improved cpu usage on IE
