I've a problem with builder: i created a new site and i tried to customize something with the builder. It works good the first time, i saved the changes and after some minutes i enabled builder again. Here came the problem. The builder interface was not like before anymore... it was different, i could not see the normal images at the right and left sides but only the little red X and the little wheel option for every thing modifiable.

The other problem is: if i continue to make changes and i save them all the tools in right and left are completely disappeared...

All is solved if i change design but once done the problems come again when i enable builder...

What you mean with: "remove widgets"? I don't want to remove them... i want to see them on my site!

And what you mean with "update the skeleton" ? just F5?

About thirdy - party of scripts i completely do not know what are you talking about!! My fault i know...but i can't understand you!
