I tried the same file in Poser 12, and it's fine. Click "cancel," and the render cancels nearly instantly.

But with Poser 13, it just hangs. Task Manager shows CPU usage is high, but nothing seems to be happening. Maybe it would resolve eventually, but after several minutes, I killed Poser. Tried it again after rebooting, same results.

Ive run into this too.  For test sake, next time it hangs, see what happens if you press Alt+F4  (make sure you saved your work before attempting, or try with a test scene).
See if instead of forcing Poser closed (as Alt+F4 normally would), see if it cancels render, freezes Poser for a few seconds, and then go back to normal.  If it does, now try to render with Superfly against and then also cancel it again once it starts.   Curious if we are getting the same results.

Yes, that's what happens! Though Poser freezes for more than a few seconds. Maybe a minute or so. But then it works fine. Superfly seems to render a lot faster afterwards, too.
