I am running Animation Lab with V17 and have seen no issues.
Don, are you able to test something in TC17 for me please?
Have you tried to create an animation involving rotating the model in small increments (ie <1 degree each increment)?
I've tried that in TC17, but I don't get what I would expect. I'm getting incremental movements much larger than 1 degree. If I try the same in TC15 I get a different result - it is more like I would expect.
Maybe this is one of the things IMSI is alluding to when they say AnimationLab 4.4 is not compatible with TC17.
