I have a weird problem on my 2011 MacBook Pro 15" running OS X 10.8.2.
Every now and then - say every two days - the system starts to ignore most of the keys I press for 2-3 minutes. It's like processing of keystrokes becomes incredibly slow. If I wait for ten seconds between each key, what I type is processed completely; otherwise kys wl b msng rndomly.
The system is not overloaded in any way when this happens. I'm usually writing something and this comes out of the blue.
Has anybody experienced the same, or could point me to some resources? I'm having a hard time coming up with a good Google query for this problem.
It is possible this was introduced by the 10.8 upgrade but I'm not 100% sure.
I managed to run
top while this occurred again and the only thing that was runnng that usually isn't is Google's
ksfetch. Will post more info if I catch it again.
