I just upgraded from jGrowl 1.2.0 to 1.2.4 and now jGrowl is using a theme from jQuery-UI for styling. How can I prevent this?

The latest HTML is as follows:

<div id="jGrowl" class="center jGrowl">

    <div class="jGrowl-notification"></div>

    <div class="jGrowl-notification ui-state-highlight ui-corner-all notification-success" style="display: block;">

        <div class="close">×</div>

        <div class="header"></div>

        <div class="message">Your search was saved successfully.</div>

    </div>

</div>

I want to use the "notification-success" class, but a bunch of additional junk is being thrown in because of the classes "ui-state-hightlight" and "ui-corner-all." that seem to be automatically included by jGrowl.

Any help would be appreciated.

Regards,
