Hi Adam -- I have just upgraded to the 4.0.0.7 release and am experiencing this same problem.  You may remember that this machine was experiencing the http:/// link and image insert problem -- and you gave me a shout that the problem was fixed in 07.

I will go back and re-upload the new release but this is a major disappointment.  I have tested the (new -  07 release?) at your demo address and all is well there (including the link fix!!!) so the problem is with the release code - or - my install.

 

Two clues:

 

1) Note that the drop downs do not populate.  We have added a code snippet to the drop down menu.

2) We are using some custom buttons in our implementation.
