Minor issues - help?

[BladeVampireSlayer]

Hi all,

A couple of things I've noticed are:

1.) Why do the torpedo control panel lights flicker when in command room view?
2.) The switches on radar panel don't seem to work so I can't seem to get it working.
3.) The button to switch on/off the recharging of batteries doesn't work. I cant seem to stop it from continually charging them no matter how many times I press it.

Also is it possible to run the electric engines on the surface? I'm low on diesel and I wanted to use the electrics for a while to try and increase my range but I can't seem to do that on the surface.
