2007 PPTX Format Sample Document Created by LibreOffice RC1

Hello!

I use LibreOffice in my daily work, but I have to exchange documents with MS
Office formats (mainly .doc/.xls/.ppt) because all others use MS Office (mainly
2003). So I pay very much attention to try to reduce incompatibility at the
utmost.

Yesterday I found a problem which LibreOffice has but OOo/Go-oo don't have.

The .ppt/.pptx documents created by LibreOffice (both of RC1 and RC2 for
Windows and Linux) can't be opened by Microsoft PowerPoint Viewer (with the
support of 2007 formats) and Micrsoft Office Web Apps.

MS PowerPoint Viewer says that the documents have a problem.

MS Office Web Apps warns that the .ppt documents have a potential security
problem ("PowerPoint Web App cannot open this presentation because it may
contain malicious content. To view or edit this presentation, open it in
Microsoft PowerPoint.") and the .pptx documents are broken ("PowerPoint Web App
cannot open this presentation because of an error. To view or edit this
presentation, open it in Microsoft PowerPoint.").

However, MS Office PowerPoint can open these documents.

The .ppt/.pptx documents created by OpenOffice.org/Go-oo can be opened by both
of MS PowerPoint Viewer and MS Office Web Apps without any warning.

LibreOffice RC2 has an other problem about converting an .odp document to a
.pptx document. An .odp file of about 500 KB (with a column chart generated
from a data sheet) is saved as a .ppt file with the similar size, but it will
be saved as a .pptx file with more than 6 MB. (Sorry, I can't attach the
specific document.)

Thanks for all people's efforts to launch and improve the great project!
