I said "check to make sure there's no stalled ones", meaning open your taskmanager and make sure there's no stalled psclients in there that didn't fully exit, and kill them if there are. (on WinXP, do ctrl+shift+esc, goto processes, find any psclient.exe ones and click them then "end process" button)
The standby/hibernation thing was just a personal sidenote. Standby still uses power, so it's not really that usefull. I prefer to use hibernate instead, for when I close my laptop. It takes a little bit longer to load back up from, but it's completely off. Just my opinion; if you're constantly opening/closing the thing, then standby might be better for you.
The keyboard is my sig... just a little sarcastic stab at idots who type large blobs of text and expect us to be able to read them...
