Fault in fixture addressing

[PeterV]

Just for the record, I have found that if I try to patch a fixture so that it uses the last n channels of the 512 available, none of the outputs respond for that fixture. Move it one address back, so that it doesn't use 512, then it is fine. I was using a fixture with 15 channels patched to 498 (which the FF chose for itself as being the highest available) which should have been fine. Changing to 497 fixed this. I am using the most recent version of the software.
