I'm using XOOPS 2.0.6. I've noticed whenever I do a "modify user", it shows my username in the nick spot and tries to change their nick to mine (e.g. if I "modify user" then immediately submit, it displays an error saying the nick is taken).

Can anyone else can confirm / dispute this? It's been there since in 2.0.5.x, maybe earlier. I don't modify users that often, but occasionally will reset someone's password. I'm suspecting it's just a seldom used function.
