Deja vu! I have to modify an old app that utilized Mr. Blacks TABS and 3D drivers (that was genius!) to build the screen sets. After rebuilding the project from scratch, something was lost within the project manager because it currently displays the 3 (in this case) windows separately in the main screen when run. I forgot how to set up the screens within the edit dialog, however, I do seem to remember that there is something to toggle on/off in order for all of them to appear as one window. All of the directives are still in the setup code of the primary and member screens and are unchanged. Thanks for any help on this!
