I have to be more clear. I didn’t have a problem with Podium. It was with SU. I was building all the sub-assemblies in separate files and then moving them into the kitchen when done. It was the cut and paste into the main file that was not working properly. The item would paste and when I attempted to position it, it would move, stop, move somewhere else, stop, move somewhere else. This would repeat a number of times and then disappear. The object just seemed to complicated for the memory I have in my MacBook Pro. When I reduced the object’s complexity it worked better. Not great, just better. Again, the rendering engine did not have a problem.
