If you can find another open source powerpoint reader (that isn't OpenOffice,

Sure thing. Probably unrelated but this simple code chokes on the same
powerpoint file but handle some others okay.

P.S. Why does getSheetNumber() keep giving me -1?
On a recent SVN checkout, it should give you one higher than the slide's
position in the array of slides. Are you sure you have a recent enough copy
of POI?
Probably not. I'm using poi-3.0-alpha1-20050704.jar and the corresponding
scratchpad.
Thanks!
