yup it should all be working,
runned cs4 with continuum complete 5 on xp 64, running it now since a few days on W7 64 bits, CS4 and complete 5. Still slow to change timeline once cc5 filters are applied, still have to wait up to 10 seconds to change filter presets despite a soupped up machine: quad core cranked up at 3.2g and 8gigs of Ram.
