After a discussion with Philipp Lohmann about my proposal, he suggested me to
file an issue and assign it to framework. 

Please note : the request is extremely important for Mac users.

As you probably know, when the last window is closed, OpenOffice.org quits, and
this is not expected on Mac OS X, because all open applications can be accessed
using the Finder.

For example : using Apple key  + TAB  allows to switch between all open
application, even if no frame is drawn for them. Chose one application with the
Finder activates the corresponding menu in mainmenubar (works already for Aqua
OpenOffice.org, but only when a frame exists)

What is expected :

1) Not draw the grey frame anymore (the one when no document is open)

2) Keep :
- OpenOffice.org open, even if no visible OpenOffice.org frame is drawn  
- the main menubar accessible, when OpenOffice.org is selected in the Finder (
works already, but only with a visible frame).


Test cases to illustrate :

Pre-requisite:  a writer (e.g. , but can be whatever else ) document is open.
Close the last document using Apple + W key or close in the menubar (supposing
this document is saved), should result in 

- no more OpenOffice.org frame
- OpenOffice.org menu still accessible ( using the Finder if not directly available)


Second expected feature (later)

Start OpenOffice.org without draw any frame :  this would help to propose a new
feature at launch : 
choose the type of document to create, or open an existing one


No idea if this is easy to do, but this is the way common Mac OS X application work.

Thanks in advance for your help  :-)
