I've installed Snow Leopard on my MBP and I get the following message whenever the screen saver kicks in:
You cannot use the Marine Aquarium 2 & Time screen saver with this version of OSX. Please contact the vender to get a newer version of the screen saver.
Will there be a SL compatible version coming? I'm bummed because I had just updated to the Leopard version of Marine Aquarium a month or so ago and I miss it already.
