I've been away from Silent Hunter III for so long now I've forgotten how to play it.
To make matters worse I've been playing Silent Hunter V a lot lately so my fingers are used to the Silent Hunter V keyboard (WASD for walking around) setup which is frustrating the hell out of me in SHIII.
My biggest problem with SHIII is the accidental firing of torps. This is how it happens. I click on the periscope view so I can turn the view with my mouse. But when I click again it fires torpedo number 1 (or whatever torpedo I had last selected).
I just want the view to lock and the mouse control back when I click the mouse 1 button. I don't want to fire a torpedo! I sunk a friendly by accident this way. My expression -

and then -

as it blew up. LOL!
How does one go about fixing this?
