A little background:

WordPress Mu (multiple user) allows many separate individual blogs to be created under one WordPress installation.

BuddyPress adds a social network layer to WPMu.

When a new user registers on a WPMu/BP site, they have the option of setting a personal avatar.  Just like you did when you signed up on Active Rain.

Except, there appears to be a slight change in the "crop avatar" function in the newest version of BuddyPress (1.0.3); and existing BuddyPress Themes are choking on that one function.  (The existing theme is fine until a new member uploads or changes an avatar... then just the one function of resizing the avatar goes wonky ... the theme continues to function otherwise)...

The default BuddyPress theme does not have this problem.  Obviously, it was updated with the release of 1.0.3.

So, okie-dokie, pokie, here's what I am going to do.

I am going to open up the css files for the BuddyPress Home and Member themes  (it's base.css in the css folder) and start messing around with background, bar, and border colors, etc.,  so I don't have to wait for the designers to rework their themes......

Gee, just what I was trying to avoid doing since free time is at a premium right now. :-)
