I use ram optimzer and that frees up your memory for you. Memturbo has a free 30 day trial on their memory optimizing software.Ram optimizer has a free version also. On another note I just got one of the BUSlink usb harddrives it works very well though a little slow transfering things(8k transfer rate I believe). I like the idea of a portable harddrive and the fact that it is non-intrusive to add it. I can operate any program on it that will operate if it doesn't need to be on the c: drive( if I remember correctly Poser 3 needs to be on the c: drive but Poser 4 doesn't) Tootles, Marge
