BTW, I am using w7x64 and have 4GB of memory (cheap laptop). Currently using about 50% with 81 processes. If any of the processes will run a lot faster by taking another GB of memory at times, good for them. Usually called statistical multiplexing. If you are running W95 with 128M of memory (or DOS with 64K :wink: ), that is a different problem than modern computer systems.
