changing setting dive when warship sighted

[entity7]

When I fist started my career I selected the option to dive to periscope depth when warships are sighted thinking it the safe option I could change back if needed. Since then it drives me nuts when it dives automatically especially when I get the same ship sighted over and over on approach. I resurface only to have the lookout again report on warship sighted and its back down to periscope depth all over again (lather, rinse, repeat, aargh!...) Ive tried to find where this setting is saved to get back to asking for orders each time and have yet to find it. Anyone know where this setting is saved and what the line should be changed to? Its change this or im tossing the lookouts overboard and maybe get a rowboat simulation instead grrrr......
