I just installed the beta yesterday. I can view the thoughts of only one of my two brains. When I try to switch to the other brain, I get a message stating that the other brain (I'm trying to switch to) is already open, but I'm unable to see any thoughts. In short, I guess I'm unable to successfully switch between two brains although both brain buttons are present. I searched the forum and saw that this was an issue with a prior beta version which was supposedly addressed by v 188.8.131.52.
