Umm, that's pretty friggin' terrible. When you restart in safe mode, does the same thing happen? Have you tried installing the nightly 'fresh', and does that help?
safe mode was the same, installed fresh and working
(In reply to Christopher Carter from comment #2) > safe mode was the same, installed fresh and working OK. So I guess we should mark this WFM, but if anyone else reproduces this or it comes back to you, we should try to investigate in more detail how this is possible... :-\
