Immediately after I installed this screensaver, my computer began exhibiting numerous malfunctions. For example, upon attempting to delete any file, I had to authenticate. After repairing permissions, the problem still remained. After running Disk Warrior, it reported no System Folder was blessed. And the only system folders offered for blessing were Mac OS 9 folders. I admit that my problems may have nothing to do with Scattered Flurries. However, I suspect that they are. At the very least, try this screen saver with extreme caution.
