I switched from Townsend Anyalytics a few weeks back to esignal for reasons I dont want to go into. I kind of like esignal, especially the overlay function as you can put a dozen indexes on the same chart but I had occasional problems with freezups. I was about to give up and change back but posts on this forum convinced me to change to Windows 2000 Pro in spite of worries about installations problems. I'm glad to say that installation was no problem at all and no more freezups. Thanks guys.
