Well, I know that I did see a bug last night. I set up a new project in P5 with a Steffy Stax character. When I reloaded after a lockup, the magnets doubled on the clothing, and both dials affect the magnet. I can post a screen shot when I get home this evening.

And the 'multiplying magnet' bug is also in P4. I can totally agree that it is impossible to completely test software/hardware compatability for a commercial application, but it is possible to fix known bugs.
