I have dual core proc on this machine (Dell D620) @1.83mhz. It's not really helping, to be honest. I need to sort out that bloody INPA! I think the problem with INPA is that it doesn't have a dedicated .prg/.ipo files for my DME (non EWS). I'm using DM331K20 now, but this one is for EWS DME's. If I find that file, I think I will be able to run INPA. Or at least, if I could somehow edit the .ipo file to skip the EWS check..
