Hi JDexter: I received my copy yesterday evening, spent the night installing it and going over the tutorials. Did several test renders and it seems faster than C2. No major problems yet but I haven't had time to delve deeper into the program. Minor problem with bringing in the test model, the grids did not show on the top and front view. Re-loading the model corrected that, but I had that issue with C2 as well. Chrisf.
