Perhaps I'm just not setting a permission correctly, but I cannot seem to give any user who is not an Admin the ability to edit text within a Text/HTML module.  When hovering over the Text/HTML module context menu, they are offered Import Content->Export Content->Help->Online Help->Print->Settings->Delete->Refresh and Move-> from the context menu, but not Edit Text (which, of course, usually appears first in that list).

Help!? ;)  Thanks in advance!

There are indeed granted "Edit Page" permissions within the Page settings that the module is assigned to.  IOn previous versions of DNN, this allowed editing of anything on the page.  (I don't recall ever having to assign specific Edit rights to individual modules if they had control of the entire page. ? )

As for DNN and Text/HTML module versions, they are 4.5.1 and 04.05.00, respectively.

Thanks a million for your advice and guidance!!
