This is the first time I've ever had this problem, or maybe never noticed it.
I created a Powerpoint file under ".PPTX", everything looked fine, so uploaded to Skydrive.
I had some slides with multiple photos, as well as some Words or comments.
After uploading to Skydrive, I ran the slide show -- any slides with multiple photos show only ONE photo. photos are off-centered, any words on the slide with a photo in it no longer show up.

Anybody else have this problem, or is it only me?
I uploaded to Skydrive the following formats, to no avail.  All acted the same.
File formats uploaded:  PPTX, PPS, PPSX
I am using Microsoft Office 2007, under Windows 7 - all maintenance up to date.

Help!
As an aside, is there any ungodly reason WHY Skydrive doesn't handle AVI or WMV files?
I also uploaded one file with AVI and one file without AVI - same results --- no difference!
