Could have been a misread (like I've never done that!!), poor phrasing 
on my part.....

Doesn't seem to be a stall; not sure the last time I let things sit but 
shouldn't take too long as I generally use 16 GB thumbdrives.  The 
system freezes: time display stops (have it configured to display 
seconds), mouse won't move, NumLock won't toggle.  Last time had the 
lockup REISUB wouldn't work but I think sometimes (rarely) it works.  

LIS most of the time the thumbdrives play nice -- most are USB 3's and 
generally plug them into the added-on USB 3 port on the front panel.  
Yesterday plugged in headphones and that locked up the system (!) -- 
that port is part of the USB 2 panel built in to the chassis.  (Still an
add-on.)  Think I tapped for static discharge -- usually do in winter 
but can't be 100% sure.

.... Cross poison ivy w/ 4-leaf clovers maybe you'll get rash of good luck.
