We currently do not have access
to the Office 11 beta. We believe that Pocket Slides 1.7 will function correctly with it. Of course, by the time Office 11 is released, we will have identified any incompatibilities and will have released a patch if need be.
The good news is that we now support users with PowerPoint 97 (and that's quite a user base) fully. Earlier versions of Pocket Slides had a few conversion quirks. So, we support PowerPoint 97, 2000, and XP (2002) at this time.
