I ran a single pass of memtest (nine tests). Passed.

I ran Disk tests in Applications > System Tools > Administration > 
System Testing. All it did was disk/detect, which passed. That doesn't 
seem like enough. I found a link that recommended using palimpsest. Is 
that the one you mean? I'll go back and run that when I have time, 
again. Should I shut down the front end  and back end before I run that 
test?

Meanwhile,
