Because I have pulled out all stops ? Well no particular reason. I've 
asked my kids nicely not to poke any /more/ holes in the security on the 
system. Probably should tighten up the ship. I have some conflict going 
on between the hardware pci USB cards in the machine, so I thought I'd 
see what would happen if I gave ASUS and whatever no-name Taiwanese I 
have in there free rein. Nothing gained as far as I can see, so I'll see 
about closing some of the more gaping holes. At least as far as getting 
rid of deprecation warnings go :-) .
I hope "they" never get serious about requiring a license to own a 
computer with Internet access. :-)
