BTW. you also can read comic book archives by MorphOS itself too. Just double click the CBR (or similar) file and it'll open as a archived directory and you can then view the files with ShowGirls for example. ShowGirls has good scaling functions to have them good looking and you can browse to next pages with pageup/down keys etc. Separate comic book reader software isn't that necessary for it...
CBR is just a RAR file. You can rename them to .rar and then unpack them. Then you will get each page as a seperate image. I can understand one wanting to have the whole comics in one file, but I prefer to have them in their own drawers instead.
