Martin Absolutely! I have seen OS9 grow from 28 to 48 MB depending on what is being done. Its really good to remember that! P4 seems to want more RAM than P3-most of my crashes have revolved around limited RAM. Now when I render anything beyond single characters against plain background, I switch on VM (leave it OFF since it screws up Photoshop) and give P4 250 MB or so to play with. Slow-but much more stable! thanks for your input! Eric
