What is it about computers and Occam's Razor anyway?? "The simplest
explanation...."
I seem to have solved this problem with a cold reboot, shut it down, left it
for a while and then powered up again and so far it SEEMS to be running
normally.... Boy do I feel dumb, I must have rebooted it a hundred times but
didn't once think that maybe a power-down would make a difference... D'OH
D'OH D'OH D'OH D'OH D'OH Just call me Homer J Simpson!
Oh well, what would life be without a good lesson from time to time!
Thanks to anyone who put thought into this for me, I'm sorry I wasted
everyone's time :-)
Have a nice weekend all, I will!
