Hello, I've just installed Mountain Lion DP2 (yes, I am a registered developer).. So far, so great expect one thing. I've installed it as a dual boot with Snow Leopard, so I can access my Snow Leopard partition under Mountain Lion and vice versa. But Mountain Lion tends to go searching for things on my Snow Leopard partition. When I do 'Open With' in ML, I see programs installed under SL.. When I want to open the file with the program on the SL partition, for some it works fine, others crashes with an error about a damaged program installation. Is there anything I can do to keep my SL en ML partitions 'seperate' from each others, so they don't search things on other partitions? Although I still want to access my home folder on the other partition so a simple unmount isn't a solution..
