Hello, This is an odd one. I was running the previous beta (5060 I think) with shared desktop and it was working great. Here's my config: Macbook Pro/ 3 Gb ram with 2 hard drives (second drive replaced the surperdrive) Boot camp installed on second disk Running boot camp installation under boot camp Mac OS 10.4.10 I updated to 5144, and now the shared profile option doesn't work anymore. Some elements are still there, but the option doesn't even show up in parallels tools, and when I tried to enable it in the VM configuration, the shared profiles tab says "Feature is not available if Hard Disk 1 is configured to use the Boot Camp." Any reason why not? Worked fine on the previous build. This isn't a deal breaker, but that was a really cool feature.
