At first glance, it sounds like your speed is off a bit. If the speed you are entering is slower than the target is travelling, your torps would miss behind the target.

OR...you are turning the PK off instead of on.....?(EDIT: never mind, just re-read your post)

It's wierd that turning off the PK then back on would reset the attack map. The PK doesn't reset it's data when you turn it off and on....at least on my boat it doesn't....
