Hmmm, then I've learned something too. :)
This delay is no secret. There is even text that says just that under the stats in an AdWords account. As I said earlier, though, I do not know if this also applies to AdSense.
In any case, since things seem to be back on an even keel in regard to AdSense logins, I'm going to stop checking back and stick with the AdWords forums now - where I'm really meant to be. :)
It was fun to be here, though, in spite of the issue that got me here in the first place. ;)
