Wouldn't it be usefull and comfortable if it would be set to the current value?

Why:

• I do not often change user data, so I forgot this behaviour.
• If I'm in the admin mask, I can't see the useres role. I've to jump back to see it.
• If I change the data of one or more admins (or other roles) and do not realise that the role is resetet to reporter, so I wonder why the system doesn't work as it ever did and need a lot of time to fix it (so happend). In the actual case the useres called me why they couldn't submit tasks to the admins.

So I would be thankfull, if you could take this issue to your tasklist.

Please have a look at the duplicate bug 0011862
The problem is already fixed, the fix will be part of the next version.
You can watch the development by having a look at the roadmap
http://www.mantisbt.org/bugs/roadmap_page.php

If you want the fix today you could
a) download a nightly build from http://www.mantisbt.org/builds or
b) patch just the two affected files http://www.mantisbt.org/bugs/plugin.php?page=Source/view&id=15233

Thanks for help and information.
Yes, I'll do so (changing the two files).
Greetings Udo
