Although I dont use anymore MS Office, I saw one colleague to use windows split
in MS Office. What is Window Split?

In your current document, you can go: Menu: Window->Split, and the Word give you
the opportunity to place a line to a horizontal position of your text. Then when
you click, the documents screen is split to 2 screens. In each screen you can
have acceess to a different position of the same document, making it very handly
when you write big documents and need to do references.

OpenOffice 2.1 (at least) doesnt have that usefull feature. The only way to do
it is to make a new window and then orgnize horizontal both the 2 document
windows. But the disadvantage is that the [windows title bars and toolbars], are
doubled that way, taking almost the 1/3 of the vertical space of the screen.
With [windows split] factionality, there only enters one line, having enough
vertical space to work within the 2 screens.

It would be good OpenOffice later versions to have that feature :)
Ps. I will not supprised if you somehow have add it, but I dont know how (so
please if you do have it tell me how to do it) - because you always are one step
in frond of my needs! ;)

Thank you :)
