[Plugin: WordPress Post Tabs] Don't see tabs (WP3.1/Weaver 2.0)

When checking the code for my WP deployment running Weaver vs. one running the Buddypress theme I noticed the following.

Under: <div class="wordpress-post-tabs">

WEAVER: (note: no classes at all)

<ul>
with (note: no classes at all)
<li> statements containing
an <a onclick="return wptReload('tabs-1107-0-0')">tab1</a>

BUDDYPRESS:

<ul class="ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all">
with (note: no onclick but it works!)
<li> statements containing
an <a href="#tabs_1107_0_0">tab1</a>

What could weaver have done that prevents the Post Tabs classes not to be added to the ul and li statements?

Why does one theme show the onclick statement and the other nothing but a #id link?

Interesting. In the settings I changed:
– unchecked ‘enable fade effect’
– unchecked ‘disable cookies’
– unchecked ‘do not load jquery’

And now it seems to be working.. Will continue to test.
In the mean time I’m running WP 3.1.2 and the latest Weaver (2.2.2)
