Howard is there any chance that you can write Quad Processor support into the Windows version of foldtrajlite to run as a service as I have 15 Dual Processor Xeon machines with HT enabled which I will be running DF on and I want to use the full Processor power. I have fudged a registry patch and put 3 and 4 in the service.cfg files but it doesn't work properly so I have to run 4 copies of the foldit.bat from 4 installs to get it to run and this is not good enough I need it to be able to run as a service can you help please
