Thank you for adding it :)
I've noticed that if you run it from WB, exit it and then run it again sometimes it freezes up. I have no idea what is causing it, but it's likely to be memory related - probably something wasn't free'd up properly.
I've done heavy testing on a range of configurations from KS 1.3 and up and I haven't experienced any issues. I have however not tested it against all the various accelerator cards out there, only the Indivision 030 MK2 I've got in my 1200.
