How can I use RADpage in cooperation with another HTML editor ?
The obvious solution is to import HTML pages using the import function of RADpage. This is fine for the inital page layout. Afterwards you can edit the heitml pages that you created with RADpage (the .hei files) directly with your HTML editor, provided that you told RADpage what kind of HTML editor you are using. Upon creation or import of a page, you can select various kinds of HTML editors to use. There is more information in the RADpage help menu, in the tutorial and in the manual.
