I upgraded to v.1.4.2 and am experiencing the following. Some may be by design, I don't know.

1. In my form views, there is now a new link at the top to edit the form.
2. When I click this, a new window pops up, but it is completely empty (no editor or anything else).
3. If I go to manage forms, the interface looks like it used to. Clicking edit for a form just populates the plain text editor. None of the nifty new editing tools are available.

1. The new link is by design. It is the link to launch the new inline editor
2. There is most likely a Javascript issue. Do you experience any JS errors? Can you include screen shots of what you're seeing?
3. That is by design. The first step when integrating a new editor like this is to provide it as an inline option. We deliberately did not change any of the standard methods for creating/editing forms and templates. The reason is that implementing a significant change like the editor - especially one based on Javascript which is notoriously difficult to implement in an 'open' environment like DNN - may not result in success in all sites. There will invariably be conflicts with other modules injecting their own Javascript. Relying completely on that editor could prevent you from being able to edit your templates/forms at all. So, the safe course is to implement the editor as a nice option and work out any kinks that pop-up, before implementing it as the default editor.

Best,
