Another option (depending on what Joe is trying to achieve) is to setup Batch Run jobs within the Analysis dialog box instead of running them interactive. This will cause just the msEngine to run which has no graphics. This frees up memory taken up by the heavy xtop and mstruct UI's.
PS. Don't forget to turn off your anti-virus software while running analyses. Depending on your AV vendor this can have a signigficant impact on your analysis time.
