No Quick look preview for IIQ files (Phase1 camera)

Hi all!

hope some one can help. I am a photographer, using Phase one digital back, Mac pro 2X2.8 GHz Quad Core Intel Xeon. Until upgrading to Snow Leopard (from Os 10.5) I could see the RAW IIQ files preview in the Mac Finder. Something i can still do with my newest Macs that came alredy with Os 10.6. The Phase 1 support team coulden't find the problem. The Quicklook generate this process, so i understand.

Can someone help me with that?

Thanks,

Ya
