If it is an exporter problem, you'll want to hack around: <a href="http://cgit.freedesktop.org/libreoffice/core/tree/sd/source/filter/eppt" target="_blank">http://cgit.freedesktop.org/libreoffice/core/tree/sd/source/filter/eppt</a> If it is an importer problem, then it is most probably around: <a href="http://cgit.freedesktop.org/libreoffice/core/tree/oox/source/ppt" target="_blank">http://cgit.freedesktop.org/libreoffice/core/tree/oox/source/ppt</a> All the best, Kendy </blockquote></div>
