Have never previously installed any version, installed latest beta. I can see and click in the menus, but there is no visible editor cursor or text. Changing color schemes doesn't help. Opening files and clicking various items in the Preferences menu seems to open multiple tabs, but they are unlabeled and I can't see any text. Possibly related, the app did want to connect to the Internet (why?) when I started it and my Firewall denied access. I'm running XP SP3 on an old AMD Athlon Thunderbird system.
