Those glass panes, how are they made? Planes or boxes? That may make a difference. If you make a glass pane from a flattened box, you'll have both an entry and exit surface. For nice refraction effects you'll have to set the raytrace bounces to at least 4. You won't get good refraction effects when you use a single sided or double sided square. The glares in real-world flat glass are influenced by slight imperfections on the surface. A tiny little bit of displacement, driven by an fBm shader, might help to get you those glares. I'd say displacement setting at the equivalent of 0.1 mm (0.004 inches). By the way, if you have Poser 6, you should use the fresnel shader. It combines reflection and refraction nicely - I've used it to make some very convincing water. Hope this helps, Steven.
