LJLogin
I think I figured out the annoying LJLogin bug, where users' site schemes keep switching to Horizon. :D
Apparently there's a cookie that LJLogin doesn't update permanently when you log in/out, which the Web interface *does*. This cookie includes the site scheme information. What this means is that if you ever use the Web interface to log out of LiveJournal, your site scheme will be set to the default and LJLogin won't update it when you log in.
So, to fix it, log *in* with the Web interface. The site will send you a new permanent site scheme cookie and you'll then be able to use LJLogin without a problem.
The moral of the story: if you use LJLogin, make sure you use it for everything - logging in and out, and switching accounts. Don't use the Web interface, and if you do, use the Web interface again to fix it.
Note: I'm not a supporthelp or admin, so can't say whether this answer should be given to users or whether we should continue giving the standard NOP replies. I'd be interested in getting confirmation on that. :)
