you can turn off the sounds just like regular ol' aim, just have to hunt for it a little....
IM/Buddy Chat, sound buttons.
The only other couple problems i see is the Aim Today.. the put it where you usually click to put up away messages... that's no good 🙁 Also, dragging files over for transfer... now it's whatever name you let go on, not the highlighted one (this can be good, or bad.. just need to get used to... actually, that goes the same for both issues)
and i don't know about the "close but minimize" issue, i don't have any problems w/ anything at all. The main window does go to the taskbar now instead of closing, but that's a "feature"... i haven't bothered to see if theres a way to change it back or not tho.
heh, one addition, i do have a problem w/ the taskbar icon blinking... it sometimes blinks after i've checked.. this has been a problem w/ aim, not just beta's, for me.
