I appear to be having similar problems to rbowlby83...
If I try and copy text to the Alfred Cliipboard and then paste it, the current item might pop up, it might be the previous item that I copied.
When I disable the Alfred Clipboard, copy and paste works properly. As soon as I restart it, it's back to spinning the roulette wheel as to what I'm going to get.
I'm using Alfred 2.6 (374)
I saved this information for now, I AM using the 10.10.3 public beta and while I do understand, respect and normally comply with not saying anything about using beta OS'es with software,
