Just installed ZD last night and added one account. Worked nicely. Now after a reboot it started a goofy screen with three icons (one was a plane) on it. Just sits there forever. Checked taskman and there is a process called Prism doing nothing. Closed the goofy icon window and Prism shot up to 50% for a while then I gave up.
