I've figured out what happened.
When I use Spybot's Immunize function, it deletes all of Opera's existing cookies.
It appears that the effect goes no farther than being required to log back into all of the web sites where a cookie was allowing automatic login.
Oddly enough, when I started checking Opera's cookies, they were all gone. I'm not sure if this is because I had deleted them all, or because Opera had expunged it's cookies due to incompatible entries. I'll do some more tests here, and add the results to this post.
Edit: Apparently Opera is saving it's cookies in a format that Spybot doesn't understand. The reason they were deleted earlier must have been my fault (I don't remember much about what I did last night due to allergy issues), but even when the cookies are not getting deleting Spybot does not see the entries it made after Opera has parsed and re-saved it's cookies file.
BTW: All of this is being done on Windows Vista x64 with Opera 9.22 weekly build 8800. This build should be released in a couple of weeks, and the weeklies are very mature. If you want to test with them, then check out the
Opera Desktop Team blog for downloads and other info.
