I am using Pligg 9.0 and have the same problems with the Avatar system, which frankly is a mess:
1. A password prompt pops up every time because the
New Password field is pre-populated; this is a bug and needs to be fixed.
2. After uploading an avatar in Paul01, it never updates to show the new avatar. It does however update in DigitalNature.
3. After I have uploaded a custom avatar, I can't seem to upload any new ones after that point; I'm stuck with either the default avatar or the first uploaded custom avatar.
At this point the biggest problem is the overall interface; when I select "I want to upload my own avatar" a textfield with browse button should appear (or should already exist), instead of forcing me to click "save" (which then leads to the "New Password" bug).
This is very confusing to describe, largely because the interface itself is confusing and buggy. I encourage any of the developers to try uploading a new avatar on my demo site, here:

... and if you can do this properly, please tell me how - because I'm at a loss to figure out how to do this myself, let alone teach any of my visitors how to do it.
