I am guessing that "cool down mode" is standby mode with the screen off.
Sometimes when you come back out of standby, the phone may take a second or two to totally wake up.
If you are talking about turning the phone all the way off and then back on, you have to wait for the SD Card to complete it's initialization before your phone will work correctly.
well i ended up turning my phone off and the notification bar is now responsive but my phone ended up getting pretty warm up to 110 degrees so i figured i'd try this option that launcherpro has but i have had the same problem twice now i really dont want to be turning on/off all the time this happens is there another option to cool my phones processor besides putting it in the freezer:reddroid:
