Nope. (Semi)City-wide blanket wi-fi. And I’m using WINE 1.3.32 on Natty 64-bit with Gnome 2 Panels.
Given the small number of users reporting the issue, and that it’s on both WINE and Windows (Product Activation Required), seems like it’d almost have to be a network issue. Especially since one user was able to register it at work, but not at home. If it’s not the firewall or router, could it be an ISP issue? That doesn’t seem likely to me, but then again, a lot of things don’t seem likely to me.
(By the way, I think I thanked you for Walrus long ago, but just in case I didn’t… Thanks. It got me through a couple of years with my old comic before the calendar thing caught up with it, at which point I put a band-aid on the calendar until I switched to Drupal and kind of rolled my own solution–based on the experience of others–with a few contrib mods and a little cut-and-paste-and-pray code-hacking. At the time, I don’t think I truly appreciated the work you put into it–until I tried and failed to make the calendar go on forever.)
