it's a wacom setting, every tablet has a different set of keys, for example i cant use a intuos pan on a graphire tablet, so a simple DLL, to make it compatible with everything will need to contain EVERY tablet's instructions, thus making it kind of complex...
anyway, great job on the program, might i ask, what's the resolution your drawing to, and how does the drawing handle? i mean, what functions are used to do this ?
regards,
