A tip on the cloth room. If a cloth intersects a figure, the simulation will hang with no notice. 30 hours later, same frame. I've also seen the frames start incrementing once a second, and go to infinity. Another indication of cloth intersection is if the cloth jumps back to the zero frame pose. Best solutions for these is to increase the steps per frame and/or the number of frames of the simulation, and select all the collision detection in the Simulation dialog (object vertex against cloth poly, etc.). Keep in mind that gravity is permanent; can't be turned off. So the greater the number of frames, the greater the affect of gravity. Another Poser expert with some great cloth tutorials is Sergemark; check out his site as well.
