Directory tree

[dieser]

I'm trying to write a program that allows the user to select folders (actually a folder specific file) from the hardrive or floppy using GUI (menu list). A couple of problems:
1) can't change drive letters while running program

2) menu list won't update as pathname is changed - found I could open a new window for the new menu and list

3) now with multiple windows I can't close them sequentially to "back up" to a previous folder so that I can move down a different path

Any suggestions???
