Desktop background

[Melvin]

I selected the acquarium plus screensaver and acquarium
for my desktop background. However, after the
screensaver has been running, I resume using my
notebook. But the acquarium background has been lost--
there is just a solid blue. What is the next step?

Aquarium screensaver uses a lot of memory and when you
return the memory has some problems resetting. I stopped
using aquarium after only using it twice. It also has
some problems with "Nemo" the clown fish staying on one
side only.
