I upgraded to Lion and am now running 10.7.2 on an "Early 2011" 15" MacBook Pro with 4GB of RAM. One of the continuing annoyances I find is the launch speed of both TextEdit and Preview. TextEdit will sometimes take around 10 seconds from launch to actually coming up. Preview often does the same thing, or it seems to load, but then automatically quits. Are there any pref files or hidden caches that I can purge to get the two mini-apps to behave normally? Thanks!
