from end users.
Here's how you can do it.
Open your form in design mode and hold down "Ctrl" & "Shift" keys and hit
"plus" key once. (Donot use the "+" on num pad) .
Now save the form using File menu - save ( Do not use Esc to save).
Now create a document with that form.
You will not see any menu bar. Cool ?
To unhide menu bar, repeat the above steps again.
It's usefull when you don't want users to select any menu options like,
runnning agents from action menu etc.
