With the interest from LOTR in using Linux for graphics rendering and other media work, having a large block of RAM available to applications ought to be standard. Or at least an easy option to switch on. Not sure I know enough about kernel hacking at this point to do a vanilla distro yet. I just need to get this promised app working for a friend. Thanks for all the help so far. r.b.
