I quickly tested it under OS4 X-5000 and at first it did not work because the tooltype is wrong (project instead of tool) and then got a total freeze ! the 68k is working fine though.
I guess it is the same bug that prevent MUImapparium to work on X-5000 hardware. Is it something to do with the non aligned memory which was removed from the kernel of X-5000 version of OS4 ?
