That 50% CPU usage will be one of your cores running flat out while the other one is idling:) Hmm... [looks at watch and wonders if it's time to post another missive about the _need_ for a redesign of FG to run on MPP systems as it gets ever clearer that significant increases in computing power have more or less stalled in terms of height (cpu speed) and in future, will come instead from width (parallel processing) - FG's current design is effectively obsolete] LeeE ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
