Somewhat to my surprise, I can now make VPN work through the wireless connection, so maybe the $12.95/day upgraded connection is worth it after all. (There's no point in doing so after Friday, however, as my work e-mail will be down all weekend.) I also need to disable pop-up blocking, because when I log in, a log-out/time remaining window is supposed to appear. If I don't explicitly log out, then I can't log back in again until the system times out. This makes moving from the wired connection in the hotel room to the wireless connection in the lobby problematic. I tried just giving permission to the ISP, but it didn't work. Oh, well.
