I am facing a very weird problem with my MacBook Pro 15". I was working in Xcode 4.2 and when I option-click in simulator (to simulate multi tap) my keyboard stops working. The weird thing is that only the a-z and 0-9 keys are not working...
By the way I am using a bluetooth mouse... and recently updated my system to MacBook Pro EFI firmware update and I am running OS X 10.7.2 Lion.
I had to restart my system to get the keyboard functionality back.
Is this a bug in the OS? How can I get rid of this problem?
Thanks in advance
