I've discovered that having the inspector showing on any game object that has bolt variables slows unity to a crawl, and clicking off of it to a game object that doesn't have bolt variables in the inspector puts unity back to normal? I used to think it was something weird so I would just restart Unity and sometimes it would go away, but now it's 100% of the time... It's almost unusable. This happened even in 1.4.1b4 before I updated to 1.4.1b5.
