Just after upgrading to Leopard, my version of Photo Mechanic, 4.5.3.2, takes a long time to open up photos for editing in photoshop cs. I am shooting jpegs and never had a problem before. They would open right away. Now it can take up to 30 seconds. And I often have to flip back and forth between PM and PS before it will show up.
Don't know if this is a Leopard problem, photoshop or photo mechanic.
