Sure thing! :)

Although, the vbox modules were only loaded, no VM was running at the 
time lockup happened. But, I've just read the whole thread you mention 
above and I understand the concern. I'll make sure the vbox modules are 
unloaded when not really needed (most of the time on that machine), in 
case lockup happens again.

Next time my daughter plays online games, I'll tell her she's actually 
serving a greater purpose, and let her take her time. :)
