Thanks for the link. I've had that problem before, too, but I then again, I don't really put showimgs on indecies below 200. I'll just use a gani for such things as its easier to make placements more exact
*edit*
The only real problem I have with showimgs is drawing priority on the Y and having to put images on layers that are more than 5-6 layers apart even if they are the same image. I usually do something like changeimgvis <index> 6 for the top image and layer 5 for the shadow. Sometimes only the top shows, sometimes the shadow is drawn overtop, and almost always they do not show up...usually drawn under the the dialog window image I use which is drawn on layer 4. It especially likes doing this on mode 1 which just draws the image with alpha only and not the gamma change to make it look like a light.
