Hi Adam,
I have upgraded from 6.3 to 6.6 but the editor failed to work in the Infragistics tabs I have used ever since CuteEditor 4.x. It only occurs in Firefox and Chrome but in Safari and IE it works fine.
The editor fails to load the toolbars and I can not click or resize the editor which is all it displays. The editors are loaded as hidden at first but then shown later.

Any thoughts?
