Yeah, this is what I kinda had in mind, although it
would be nice to just tell the damn OS to wait for
a while via some Registry setting I don't know about.
I *suspect* if I go the below route, the OS will still
try to init the damn thing before it's ready, and before
any "reset" app I might run will kick in...
