Issue with BuddyBar and Twenty Eleven theme (1.3?)

[j.conti]

Hi,

There is a issue with BuddyBar and Twenty Eleven theme.

When you are logged in, you can not select the drop down menus on BuddyBar.

Seems the drop down menus is under the theme and when you put the cursor on the drop-down menu, the drop down menu disappears.

I can't reproduce this on a clean installation of WP 3.3 + BP 1.5.2. Are you running any plugins that may be injecting additional styles, which could be responsible for the oddness? Have you tried analyzing with Firebug?

Is a clean installation and I only have WangGuard but if If I disable WangGuard, the issue remains.

The installation is a WP 3.3 Multisite + BP 1.5.2 on sub site.

​http://wangguard.org -> main site (Multisite)
​http://network.wangguard.org -> BuddyPress (Sub site)

I used Firebug and if I change the value z-index from 1000 to 9999 on buddybar.css (​http://buddypress.trac.wordpress.org/browser/tags/1.5.2/bp-core/css/buddybar.css), the issue is fixed. This is because #branding css on Twenty Eleven Theme was modified 7 weeks ago.

#branding {
    border-top: 2px solid #BBBBBB;
    padding-bottom: 10px;
    position: relative;
    z-index: 9999;
}

If you change the value z-index from 9999 for a value minor to 1000 the issue is fixed too. ( ​http://core.trac.wordpress.org/browser/tags/3.3/wp-content/themes/twentyeleven/style.css#L503 )

This problem was introduced 7 weeks ago -> ​http://core.trac.wordpress.org/changeset/19302/trunk/wp-content/themes/twentyeleven/style.css Was for fix this ticket - ​http://core.trac.wordpress.org/ticket/18938

Sorry, I forget to add the BuddyPress CSS:

#wp-admin-bar {
    font-size: 11px;
    height: 25px;
    left: 0;
    position: fixed;
    top: 0;
    width: 100%;
    z-index: 1000;
}

This is the BP Style z-index, changing from 1000 to 9999, the issue is fixed.
