I've got a curious problem with my computer, which is set up with 2 spaces. I use the
Move left a space and
Move right a space shortcut to switch between them.
Quite often, particularly the first time I switch spaces after rebooting, OS X just switches back straight away. The sliding animation finishes, and then - just as the desktop icons would ordinarily start to fade in, or the key window would appear highlighted - it switches back, putting me back where I was. Subsequent switches work fine.
For something so minor-sounding, it's surprisingly annoying. Has anybody else had this, and managed to fix it? I'm not really sure where to begin looking. There are no messages in the console.
OS X Lion 10.7.5.
