When I click on the iSilo.app file, my Mac OS X tries to open it, you see the icon appear very briefly on the dock but then it disappears. Every time I click on it the same thing happens. This was the behavior from the beginning. I have not been able to get iSilo to open at all. I've also tried dragging .pdb files onto the iSilo icon, but that causes the same behavior mentioned above. Any suggestions? I would very much like to get iSilo to work on my Mac.
