I have noticed that the system tray temperature disappear within 1-2 hours with the latest version. I had RC448 before which has the old tray popup and there weren't any problem with it. I tried to set that it is "Always show", but next time when I start the computer it is "Hide when inactive" again.

I run Windows XP SP2 and the problem occurred only with the new tray popup.
Did anyone experience this problem? Any solutions?
Thank you for the answer in advance.
