Well kept building 2.5 every now and then .. May be I can give some hints on physics solvers ? Joe may want to ask me .. ( using ^this^ email in private ) other than that .. I'll try to squeeze some time out off my schedule to investigate the given files. BM P.S. 2.5 is going amazingly well, respect!
