Moving File Locations

I've installed OpenOffice and manually changed the default file locations to a documnent directory of my choice. For Example:

Calc doc will be saved to: C:\My Documents\Spreadsheets
Writer will be saved to: C:\My Documents\Word

You get the idea....

Then I save the changes, and exit OpenOffice. When I open OpenOffice again, the default setting are back, and my changes are gone.

How do I get them to stick?
