Yes, I did and asked for a refund. I've bought just about every Python app that has been released ar DAZ and have been very hapy with it, but not Morphos. For one thing, I thought the updates would occur as you were using the sliders, in real-time. But also it is very unresponsive. It might appear to be locking up, but it's just responding VERY slowly. Just right click on the Python tab in your taskbar and select CLOSE. Poser should be okay after it closes. Mine also kept popping up with an annoying Python script window every time I would do something. Maybe our versions are corrupted. I often buy things from DAZ as soon as they are released, and they often email me with updates or notices saying the files were corrupted. So it's deinitely within the realm of possibility. Good luck!
