We have similar problems with PV-Wave running on a VAXstation (VMS/DECwindows). We do mostly image processing, and aside from limitations on image size, doing common things like contouring a small (200x300) image runs into memory problems which boosting pagefiles and quotas to inordinately large sizes doesn't help. I believe the combination of VMS and DECwindows makes for a bad platform for the kinds of things that we, and probably you, do (at least for PV-Wave). We're installing the test version of Point & Click on our Suns, to see if that works any better for our purposes. I don't foresee us continuing to try to use the VMS software much longer.
