Ok, I've trawled through a few problems about this very topic and no one, to my knowledge, has found a solid fix to it. Basically I have a user defined form on my silverstripe site and when I create my fields and then drag them it doesn't let me. However if I refresh my browser I can then drag and drop my fields to where ever I want. Is there any way this can work with a browser refresh?
The reason why drag and drop doesn't work is the fact that the events aren't binded correctly to the DOM nodes. There are some fixes in master for it (rather than 0.2 release) and a couple more changes I've yet to push as still discovering edge cases in some browsers.
Cool, thanks for that Will.
