"When I have desktop effects enabled, there are times when I click something and the screen darkens for up to a minute before anything happens and after that my computer runs slow. When I turn off the effects it fixes itself. I have a one year old computer running two gigs of ram. This should not happen." Juanita - restaurant serverNoted this myself and not quite sure why this happens. I only run effects on my demonstration laptop...only so long I can tolerate wobbly windows and pretty sparkles before they get annoying or in the way of my work.
