Hey all, my macbook pro's cursor vanished and i wasn't able to do anything last night and i had to resort to manually turning off my mac with like 5 applications open (felt like crap having to do that). Once i rebooted my mac, everything was fine except one thing. When i go into the URL bar to type inna website, i usually double tap to hi-lite the whole url and then type over it with the site i wanna go to. I've gone to the settings and trackpad section and put the "double tap" speed to fast. and it works for the time i'm on, but once i put my mac to sleep or turn it off then back on, the double tap doesn't register anymore. other things i've realized thats being effected by this is that, i cant even open chat windows in ichat by simply double tapping the person i want to chat to. i tested out using a mouse to double click something, and still the same thing....doesn't register the double click. anyone have/had this issue? i believe it was caused when my cursor randomly disappeared and i had to manually reboot. Thanks for your time to read all this! hope any of you can help me out.
