Hmm.
Was on 5739
Ran Microsoft Antispyware Updater, and it claimed it was going to 5743.
Opened Microsoft Antispyware, said it was on 5743.
Did File, Check for update.
Said it was on 5741, and was putting in 5743.
When done, Help About read 5743, with a current timestamp.
Did File, check for update, and again cycled 5741 to 5743.
I recommend waiting a bit on this one--looks like there was a quick change
that hasn't propagated.
