This reply is a bit late - I spent most of the last four or five days troubleshooting problems with my WinXP installation (as it turned out, it was Yahoo Desktop Search indexing my drive that was causing my problems - including BSOD).
Regarding the license error that I reported, I am running Maxthon behind ZoneAlarm Pro (latest build) and access the Internet via a proxy (GhostSurf Platinum). However, I did try disabling the firewall and the proxy with no luck, though as I stated, registration did work despite the error message as I received my license via e-mail within about 5 minutes.
I was in Seoul - Mapo, Chongno-3-ga and finally Kil-dong, though I spent the entire four years working for Sisa-yong-o-sa in Chongno. I really miss the markets and hiking in the mountains outside Seoul. My wife, my mother-in-law and our pug used to go for long walks and picnics on Sundays. Somehow, we never find time for that kind of outing now that we've settled in Canada (Vancouver Island). Strange, because nature is so accessible here. I guess we just take it for granted.
Anyway, I will definitely look you up next time I'm in Korea. I am craving al-tang and Cass lager. Strange, but true.
