Does the adding/editing an anchor link work for you in TinyMCE for EPi7?
For me, it does, but it keeps getting lost (not being visible in TinyMCE). Also, it doesn't ever work to edit the anchor, when I click on the anchor in the top menu (it's clickable), it doesn't load the old string?
The same thing works fine in EPi6 R2.
There is a reported bug for this when using Chrome. IE works as expected but I don't remember the state for Firefox.
It does work in FF as expected, if this is of interest to someone reading the post :)
