System preferences freezes
After Lion install, tried to change wallpaper in system preferences. The Desktop/Screen saver screen appeared but immediatly froze. From that point on I cannot open up the System preference pane as it immediatly freezes if I try to open it. Have to "force quit" each time I try to open it. Tried to erase the PRAMS and delete the cache but no luck. I see in other forums others having same issues. Anybody found a solution? Thanks!
