Intensity Pro - No video preview in Apple Color

Hi,

I've been running Color 1.5.3 on Snow Leopard 10.6.8 with a Blackmagic Intensity Pro and all has been working as it should.

I decided to upgrade to Lion and now Color won't give me a preview through the Intensity Pro. This happens when I am going through the rooms, however, when I hit the render button I get a preview.

I've upgraded the Blackmagic drivers to the latest and I still only get a preview when I render. It is working fine in FCP just not in Color

Has anyone else experienced this?

Thanks

Tony
