[Fractint] environment space for Fractint under XP

I received this plea for help. Does anyone have a good answer? <quote> I have been unable to get fractint to run on my XP Pro SP2 computer in a Command Prompt session.  I keep getting the error R6009  not enough space for environment. I have tried several things like setting CommandEnvSize=2424 environment variable, to no avail. </quote> Tim
