Hey, a while back it was considered "bad form" to unplug a PS2 mouse from a computer that was running.

The consequences included "blowing a mouse port". Not knowing exactly what that
entailed, but wanting to err on the side of caution I've always been careful to make sure not to mess
with (un)plugging a mouse from a running computer.

So my question is twofold.

1. Was this ever a real issue, or did it just happen once to someguys cousin's boyfriends' sister?

2. If this IS/WAS a problem, have motherboard manufacturers figured it out yet, and stopped making
crap motherboards? or do we still need to be cautious?
