I used the firefox extension into Exchange CPs once and i got a banned screen, it was odd, and i logged out, but i did log back in, but i was curious to know why the screen came up
It's a random bug that's got something to do with the cookies, I think. Nobody's been able to track down the exact cause, but logging out and back in always seems to fix it.
