It kinda of works. I do get regular crashes indeed. If you use the "window sets" function, recalling your favorite windows setups, you'll see a nice graphic bug. (check my post called "Look at this" for a preview.) Can't turn off the sequencer but that's not a DP exclusive, it's a bug period. My advice, install it if you really need to use it or wait until they make it usable for pro applications. Right now frankly it's more like a toy to have fun with but you can't seriously use it reliably and efficiently, at least on OSX 10.3.2 with DP 4.12
