Just read Michael's Canon 7D pre-review, and his comment regarding crashing apps coinciding with a recent installation of Canon DPP. My guess is, Michael probably just recently also upgraded to Snow Leopard, which was crashing my Photoshop (CS3 AND CS4) & Lightroom2, and even PhotoMechanic! And this was even after the 10.6.1 update. Needless to say, I booted it out and am sticking with Leopard 10.5.8 until further notice.
So, my guess is, Canon DPP is not the culprit.
Any similar experiences?
