I have a very similar problem. After Vista has been in sleep mode, I get a box saying there is an update available. When click to update, I also get the "need administrator level to update". However, I don't have to reboot to update. I just bring up SAS and update manually. Although twice it has happened after my scheduled scan overnight and when I start un the morning I get the message but when I try manual update it tells me there is no update. Not a drastic problem but would be nice to have it fixed.
