OK 3 problems.
1. Every so often when I try to use space to play/pause a video or music file...it slows the file down like the "-" is supposed to do. I can "fix" this by going into the preferences and resetting it to be Play/Pause, even though it's already listed as being Play/Pause
2. Space wont' work any more if I touch the time bar to skip to a different part of a video. But it will if I play the file from the beginning without skipping aynthing.
3. Sometimes the acctual setting of Space as "play/pause" will be forgotten entirely much in the same way as the first problem.
