yeah, slides are tricky little guys. we had a bunch of blocks with solid hatches, and the slides looked all fugy. so we tried firing the SHADE command on them before shooting the slides, and suddenly the slides are a couple megs each. you'll have to turn off the layer your image is on before shooting the slide, or look into making the dialog box with VBA where you can just drop in a preview pane rather than rely on slides.
