Actually I was referring to the latest OSX update... But I see your right, Toast has been updated to .6. I was still having problems up to version .552b.
When I checked the Roxio support group and someone said his connection was stable with the 10.6.3 upgrade, I decided to try it again and updated to .6 at the same time. So I actually don't know which bit of kit solved the problem. Ironic considering the finger pointing going on.
But all's well that ends well. Toast is finally working the way I had paid for...
