I can't load or save bitmaps!
When using the original CDROM filesystem of AmigaOS 3.1 all filenames will be in capital letters when copying DS to your hard disk. Then all loaders and savers will not work.
Please open the drawers "DrawStudio/Module/Bitmap" and "Load" and rename all files to lowercase or use another CD-ROM filesystem - like CacheCDFS or AmiCDFS (from AmiNet) for example - to install DrawStudio.
