Ok another test...

in the med -version 6.902- I load one model of the models I used in my project
and then from File menu ->Engine Preview
the process "acknex.exe" take in the task manager under column "Mem Usage" = 31.392K
but when I load the same model in the med -version 6.894- and do the same
the process "acknex.exe" take in the task manager under column "Mem Usage" = 24.144K

please see the difference it is only one model!

again wait for your help JCL

thanks
