Well two bugs I've found are: 1. when attaching a prop to a body part, if you click on the Bend to Body part check box, PPP somehow messes up the menu system. You can' click OK to get out of the hierarchy list. Instead you have to click cancel. This then leaves all the menus grayed out and un available but yet you can still use hot keys and such. When exiting the prop's properties dialog can be seen under the main menu. 2. The drop to floor function wigs out for some reason popping my figure up 7 to 10 units on the y axis. Changing to a different pose sometimes fixes this.
