I have posted this in Alpha release thread. So in Offline Messages page, if i click any of Store sub options radio buttons it deselects Store and selects Drop automaticly. So one has to click Store again.
Clicking in “Per-user offline message storage limit:” input area is dropping focus to Drop as well.
and you know what? there is still another bug in there, though it acts a little different now. But it STILL demands " Please enter a store size greater than 0 bytes." if i select Store > Always Store and there is 0 or nothing in Limit size input area.
this issue is here back from 2.2.0 or even earlier
