I've had two big problems with Messages and all my friends have the same problems. First, typing anything in the Search box would beachball the app indefinitely until Mavericks. Second, there are issues with messages not being sent and having a red exclamation point by them – that has happened so much we have a backup Skype chat for when Messages is acting up. Also Mavericks removed the ability to disable graphical smileys :(((((( (Is there a workaround or fix anyone knows? please tell me!!) I mostly use Messages on Mac but use iOS some too. There's a huge problem on iOS which is scrolling to the bottom when people type stuff, which prevents you from catching up on conversations until everyone stops talking. That's super frustrating. (Auto scrolling to the bottom when you talk, on Mac, is also annoying. I want to read through chat I missed, reply to things as I go, and not lose my place. You have to open a second copy of the window to deal with this.)
