But in MS Word, when one closes the last open document, the grey screen is not a new document that you can start typing in - it's just background. You still have to click on File/New or File/Open. Personally I also found the Start screen (where one can choose a type of document or open a template) a bit of a nuisance. Someone reported on a way to skip that screen both at start-up and on closing a document back in the days before LibO, and I implemented it, and carried my profile over to LibO, so it works that way. LibO now starts directly into a Writer doc (NOTE: I do NOT have a script that calls LibO with a parameter). I'm not sure whether it was in the preferences, or somewhere in the menu system that this setting was found, but it was well-hidden.
Unfortunately, I have forgotten how it was done, and I haven't yet been able to find the original references to it by searching the archives at OOo.
If anyone sees this and remembers, please let me know. It will also help the OP.
