so lately i've been having problems with my dock. it was really random, and it's acting really wierd. often, when icons on the dock are ctrl-clicked, say to hide or quit the program, it won't do anything.. then when i try it again right after it will work. it pretty much always works the second time, but not the first. also, in programs like Aperture and VLC, when you go into fullscreen, the dock doesn't automatically hide. it always used too. i've tried to fix it by repairing permissions, "killall Dock" in terminal, and rebooting.. and nothing works. it's really annoying. any ideas?
