That is Poser, but it isn't a 'problem', per se. Draping frames are for just that; allowing the cloth to settle into position, and are totally unrelated to actual posing parameters. When you zero the figure's joints, that also sets them as the keyframe for frame 1 in the animation pallete (as any cloth sim is an animation effect). You could twist the figure into a pretzel, start draping, and as soon as you leave that phase and move to actual simulation, the figure snaps into the position set in keyframe 1 (unless you have spline editing set; then it will unwrap itself as it goes through the drape frame count, until it reaches the zero set in frame 1). Gebe is right; when you import for a still, you pick the single frame out of the animation, and enter that one in the import frame field in Vue (Import frame X of Y). From my experience, I would suggest setting draping to 10 frames as a matter of habit. No matter how well you did your mesh forming in the modelling stage, it takes several frames for things to resolve tiny issues in fit and cloth self-collision. Another tip. If you make your chosen pose frame 15, then plan to render out at least another 10 frames. Unless you have set the animation to the linear mode, then the model will spend the time from frame 1 to frame 15 -moving- into position (this is due to spline mode; it interpolates the movement between keyframes, where linear mode simply accepts the values between frames, and you have to do that work for yourself. So you really want to use the spline mode. It avoids all sorts of issues you get when things move too quickly). So the drape you have at your chosen frame 15 will still have the implied forces at work; ie, the cloth will still be in motion. You need a few more frames in the sim to allow things to stop swaying and settle. Oh, one 'gotcha!' using spline mode. It assumes that there is always another keyframe after the current one, unless told there is not. So if you zero the figure at frame 1, set you pose at frame 15, and render out a 30 frame simulation, the last 15 frames will have the figure twisting itself into the kinds of shape that Steven King dreams about. You can avoid this very easily, though. Open the animation slider at the bottom of the Poser window. On the right button bar, the middle button looks like a key. Press that, and you bring up the keyframe editor. There should be 2 green vertical strips in the editor field; one at frame 1, where you zeroed the figure, and one at frame 15, where you posed the figure. Left click over the one at frame 15, so that the raised hash mark is over the green line. This selects frame 15 as the active time frame. Go to the button bar on the top right; the very last button should show the message flag 'break spline'. Click it, and you've just told the spline interpolator that there are no more frames, and this is the stopping point. The figure will hold the pose at keyframe 15 for the rest of the animation (unless you change something in later frames, which will create a keyframe at that point) Make any sense?
