So installed Lion tonight all excited to be let down by quite a few things but nothing as big as this. So I have the 2011 MBP 2.3ghz, so in SnowL my monitor worked fine, it connects to the Thunderbolt port via a dvi to display port adapter. When I plug it in the computer I think the first couple of times the mouse would stay but the last time I did it the mouse disappeared but processor will go up to 50% I think config or something does it, also system prefs won't open and when you pull the monitor out the computer will just freeze. So my external monitor is now a brick. Any ideas?
