I have a problem with XOOPS 2.0.5.1 and comments in news. When i select comment mode (Nested for example) and press Refresh, everything is OK. But when i open these comments other time, i see it in Flat mode. I always see comments in Flat mode after entering my website again. Default mode, selected in Admin Panel, is Nested. But if i am logged out from my website (visitting as anonymous user, i mean), i see comments in Nested mode. But when i just log in with my user account, i see Flat mode again. What's the problem?

Edit account => Comments Display Mode
