>>My outline is a treeview :). Basically, I have a small .prg which instantiates the login form; the login textbox is removed, and the form shows some logo and a treeview (will add a menu with the same contents as in the treeview, later). It calls the forms, reports, maintainance routines (hooked to clicks upon nodes in the treeview), and serves as a general repository of globals of any kind (well, that's the idea).

>Is a "treeview" like Windows Explorer? That would be too complicated for my users. A menu would work much better.

Yes (left pane of Exploder), and in my case it replicates the contents of the meny. The primary reason for this is that I have lots of apps where the menu structure is very rich, and goes three or four levels deep. In FPD I kept the menus/popups open until explicit exit (via ESC, left/right arrow, click outside), but couldn't find a way to do it with Windows style menus. I find it very inconvenient to keep remembering where did I find something in the menu tree; more often than not, it happens to me that I forget it as soon as I find it, and then it's another ten or more minutes' task to find again.

With treeview, the last item selected remains open, selected, and visible, and doesn't rollup as soon as you click on it. That's the reason. Of course, I intend to keep _both_ the treeview and the menus.
