Hm... Dreamlayout's working fine for me. Does it still happen? And, if yes, let me get the sequence straight:
0. No buffs are on the player
1. The player is buffed. Buff icons (the little pictures) appear, but abbreviations and timers stay hidden. Buffs are not cancelable by clicking. No tooltips available.
2. One buff fades, all other buff icons behave normally now
3. Nothing interesting is happening when adding new buffs at this point
4. All buffs fade or are canceled
5. See 0 and following
Is that about right? Which containers are you using (a list of all active ones, please). Which buffs are you having?
Yes it is but i think i found the problem. I disabled Buffalo ingame (ad addons before you login) to test Buffalo2. After totally removing it from my addons directory all was fine.
