This is may be something you already know, but there seems to be a bug with the State diagrm display. I try to layout the diagram to nicely see all the states. When I leave the page then go back to it, I cannot access the bottom part. The Slider does not move to the bottom or is not existent. Only option appear to use the regenerate which creates something not easily readable. I would like to keep my layout and be able to see/modify it as is.

If you can. Send me an example (via PM) and i will try to get it logged to fix on the next release.
