I basically reworked my computer, installing XP pro (instead of home) and reinstalling all of my software (which I'm still doing -- you forget how much there is to install). On my other configuration, I had constant problems where Slimserver and SB would hang. I have no idea why. Sometimes a reboot would fix this; othertimes, it would not. On my current configuration, not one hang as of yet. No problems, actually (though I do admit that I'm afraid to change settings; it seems as if changing settings is what brings in the bugs).
While I'd like to see a better interface for slim server, whatever problems I had with slim server/SB seem to be fixed by a complete reworking of my computer. The extra 1 gig of RAM I bought might have helped, too. XP pro may also be helpful, as could the RAID controller I installed and am running off of.
