quicktime player does not respond to space key
This is driving me crazy. Sometimes when a movie is playing, I can pause it and resume with the space key. Sometimes, I cannot. I cannot tell when. It will work with a movie, then I'll go away and then back to the very same movie, and it will stop working. Pressing space key will just beep and nothing else happens. I have to click the "play" triangle in the interface to play the movie. Then sometimes the space key works again. Very intermittent and I cannot tell why it happens. I'm sure I'm not the only one... or am I?
