LibreOffice default save directory [SOLVED]

[cwr]

Does anyone know where Libreoffice (bin) 3.5.3.2 records its path
settings? For some reason it won't accept a change from the users
home directory as the default path, so I need to edit it by hand.
There seems no trace of the path strings in the usual dot directories.

Thanks - Will

Solution:
I tried emerging libreoffice- bjn with and without the java flag, and
neither allowed path editing. However, I then found that openoffice-bin
is still in the tree, and that works fine and allows me to use my OOo
code without changes.
