Why are my tubes closing themselves?

[Benzin1973]

What i cant understand is why it started happening now, i have allways opened my tubes the same way, and it dint happen before.
I will try the methods you suggested.

As some of you suggested, I guess the obvious way to fire more than one simultaneously would be to use the salvo feature! There are two reasons i dont use it:
1 - There is some diabolical bug in my brain that makes me allways forget to set the spread angle, so i end up watching my torpedoes pass in front and behing the ship
2 - Firing one at a time, i get twice the morbid pleasure of pressing the Fire button.

I guess it would be best to post a sticky on my monitor, or get a tatoo that says "set the spread angle!" And start using salvos LOL

BTW, i notice some people give tought to wich tubes they are going to fire, i usually just select 1&2. Is there a reason i should fire the tubes in a particular order (e.g. 2 & 4 or 1 & 3, etc)?

Thanks for your replies guys
