But that's a big kludge... Win95 is somewhat flawed (in this sense :-) because it first loads the .exe file into its cache buffers and then copies it from there into the program address space. Of course this (temporarilly) uses twice the RAM actually needed. This is one thing that is supposed to be fixed in Win98! So you could try to move to Win98 if you dare, :-) or use 512 MB RAM as Bob seems to do... Bo Persson bop@malmo.mail.telia.com
