Not sure if I asked this before - when my secretary creates announcement slides on her Win7 pc, they often show up as blank white slides on my pc AND the sanctuary PC when I open the presentation, but look fine on her pc. I have to have her email the slide material (usually a jpg or PPT slide) and then manually load it into the presentation. I've had it happen just once on a slide created on my PC, but it is a regular occurrence on hers. Any ideas on what might cause this?
