I've got an interesting issue going on and Google doesn't seem to be turning up much for me. I'm running Visio 2007 SP1 on Win Vista Ultimate SP1. I downloaded HP's shapes for their servers so I can diagram my server racks. I also made a couple of my own images (just some jpgs) for devices I couldn't find shapes for. For some reason several, but not all, of the shapes keep "disappearing" even though the shape is actually still there. If I mouse over the empty space, the cursor changes and I can click and the shape reappears, but as soon as I scroll, zoom, or save, they disappear again. This is quite aggravating. I've tried opening the document on an XP machine and got the same symptoms.
Ideas?
Thanks!
