screensaver not running-goes straight to login screen

[chromewaves]

hi- when i run my screensaver, either through my screen saver launcher on the taskbar, or just let windows run it at the designated time, the screen saver doesnt run at all-it just goes straight to the login screen. now if i click the preview tab on screensaver properties, it'll run, but it wont run normally. i thought this was being called by a program called processguard, so i uninstalled it, just to find that this wasnt the problem. can anyone advise as to whats wrong? or do i have to live from now on without any screensavers? i never knew how annoying it could be not to have a screensaver working-till now ;(

thanks in advance
