I've an HP intel-based i7 laptop with nVidia MX150 and it is extremely buggy. The zooms often just stop updating and stay the large, bloated, fuzzy star images. Many labeling elements just do not draw -- for example I was on M104 and its label didn't appear about 50% of the time at various zooms. I can come up with other random examples.
I asked for a refund with promise of deletion of app and destruction of registration codes. There was no physical delivery, and I am not aware of any DEMO availability to test prior to purchase? Does Simulation Curriculum not back up their products with 100% satisfaction?
