I always have my sounds off in AIM by going to the preferences and clicking to not play any sounds. But last night an upgrade button came up with AIM and I upgraded to the new version, I guess. All my sound buttons say the sound is off but whenever someone IMs me it clicks. Not just when the window pops up but with each new line in their screen. How can I stop it??? If no one knows, where can I get the previous AIM?
