That was a very brief flirtation with Expression Media for me. I downloaded, installed it on my system that I just upgraded to 10.6.4 (that has been rock solid for me, so far) and asked it to create a catalog. Within minutes it had crashed my whole system, which I don't think I ever recall happening to that degree. The finder couldn't even recover from a force quit and I had to do a hard restart. It is quite possibly something system specific for me, as I have read of others here using and liking it, but I don't need it desperately enough to venture another try at it right now. Thankfully, as a Phase One owner, I have no quarrel with the price.
