I did the thunderbolt update few days ago and now I realize that when I plug my second monitor (samsung 2232bw) by thunderbolt adapter to DVI all the system become unstable. The trackpad is jumpy and erratic also the text cursor or scrolling windows. It's not happening with TV by HDMI adapter.

I'm thinking about undo the firmware update. I found on apple's site a Firmware Restoring CD but didn't find for my MacbookPro model (Model Identifier: MacBookPro8,2 on System Profiler)

Does anyone have any idea or knows what is the correct cd?

My mac: Macbookpro 2011, 2.2ghz i7 15''

Thanks
