what does the following code do?
1. Positions the debug window to the right
2. Keeps a test button underneath the debug window
3. Creates a dynamic tree window on the left
4. Creates a text window underneath
5. Reads a URL for getting a list of folders and paints them in the tree window
6. Expands and collapses the tree using dynamic data
7. Tree window scrolls
To be done
1. when an item in a folder is selected, put the text in the text window
2. Simulate an outlook kind of interface
Special Note
To make the code fit, at a couple of places, I have broken long lines between quotes. If you want to try this code you have to reattach those lines.
