Well, maybe I can add some additional comments. I am new to BBO and also new to the Apple community, having just bought a MacBook Air, as a second computer (always been a PC person). Started using it less than one week ago. As for old and new versions of BBO, whatever comes up when I hit the shortcut is what I'm using. Assume it is the "new". I am having the exact same problem with freezing. Interestingly, when I log out and then log in with my PC, NO PROBLEM. I have left my partner waiting for my response many times while I sit and wait for something to happen with a robot. Sometimes is unfreezes but it is basically non-functional. Once I got a string of error messages saying it couldn't execute the commands. So it seems to be something unique to the Apple. I have cleared the cashe and have the newest version of Flash Player installed. Any thoughts?
