PowerPoint 2010 support
PowerPoint 2010 is still in beta, so there's not much support available for it.
There's a Microsoft sponsored tech support forum for Office 2010 beta here
Try posting to the beta forum here:
This takes you to the PowerPoint section of that forum.
This takes you to the general Office section of the same forum.
And some of the PowerPoint MVPs and other regulars in the PowerPoint Newsgroup are also working with PowerPoint 2010 and may be able to help.
