Different problems: Login level & Account details

Hello,

I've different problems with jOpenSim.
I use the jopensimregister plugin too.

When a user register and directly login on the website, the Account Details ar not displayed. The settings can't even be edited.
When the user don't login on the website, but FIRST on a viewer and logout on the viewer, then the Account Details are displayed correctly when the user login on the website.

Another problem:
I can change the Login Level from a user ONLY when the user has never logged in on the viewer. Once the user has been logged in on a viewer, the Login level can't be changed any more.

What might be the problem?
