[woobla]

Hi guys, I am having trouble with a couple of things. I just purchased SH5 and have completed the intro mission. Perhaps I am just stupid but I can't seem to find/do the following.

1. When I push (battle stations) there is no audible alarm if there is not one in the game how do I add one?. My crew seem to do nothing.
2. When I am on deck with binoculars and I lock onto a target and press space, once or twice the deck gun does not fire at a target
3. How do I get the sonar guy to call out targets? or tell me what targets are, speed, heading etc.
4. There used to be a list of guys you can click on for them to do things e.g blow tanks, run on 1 engine to charge the other etc. Is this not here anymore?.
5. I am using AUTO target etc.. on medium settings yet none of the torpedos seem to hit and a firing solution does not seem to stick with a target.
6. How do I make this more workable? is there a SH4 mod, or SH3 mod that makes it feel more real?. SH3 was king to me. SH4 was ok. At the moment it is feeling to 'arcadey'.

Any suggestions?
