Form4 building menu problems

Hi everyone,

1. My menu editor defaults to tree mode instead of list mode as Oracle Form User's Guide says (Page 18-8). So when I open a new menu module, select File, New, Menu, the Menu editor is in tree mode. How can I set the default back to list mode?
2. In list mode of my Menu editor, the name of each menu appears above the column in which it is displayed and only the individual menus are displayed in tree mode. This is totally conflict with Oracle Form User's Guide says (Page 18-8). This causes all statements of the Guide concerning the mode reversed. Which is correct?
3. When I open an existing menu , select File, Open, xx.mmb, I got an empty Menu Editor. How can I open an existing menu then?
4. When I try to generate a menu after set the properties of the menu module, I always get MNU-10633: Main menu xx not found in module, which I cannot find the error message info from SQL*Menu User Guide and reference. How is wrong here?

Please email me if/when possible since I seldom to read news.

Thanks very much in advance!
