Impress Not Creating Multi-image Handouts Properly

I have a problem with Open Office 4.1.6 Impress on Windows 7 32-bit. I want to create handouts, 6y images per page, with Order "Top to bottom, then right". If I select the default slides-per-page, then I get what I want. But if I select 6 slides per page (which is the default), I get the "Left to right, then down" orientation, even though I have explicitly selected the other order. Is this a bug? Thanks.
