Screensaver Issue With Multiple Monitors

I just setup a dual monitor layout for my PC, one on DVI-I and one on VGA. However, since doing this, I've noticed that custom imported screensavers, like from wincustomize, do not appear on both monitors, which may lead to burn-in issues later down the road. The default screensavers, however, that come with windows work fine and appear on both monitors.

Is there a way to make the custom screensavers support multiple-monitors?
