I dunno know about later versions, but with the PPL3 warez that came with my K20D, I can (and do!) drag numerous RAWs from an image browser (I usually use XnView or the Windoze file manager) into the RAW developer, and save them all as JPGs with the same settings: contrast, WB, Vivid|B&W|etc, sharpness, all that stuff. No hassle! In fact, I'm batch-processing a few hundred RAWs right now, in batches of maybe 10-30 at a time -- each batch shot in the same conditions.
OP, try that will your RAW developer warez. If its internal browser|manager won't let you open multiple files, try dragging-in a few from outside.
