1 - try using Dan Fraser's spysat mod instead, just two little files that dump into your SH3 main directory, no JSGME. Works great, shows each individual ship (great for finding the very fast ones - like troop ships!).

2 - Could it be that you're out of ammo? It carries too little ammo, and your crew will go through it very fast if you don't limit their shooting distance to at least medium range. I find the main gunners can't hit squat, it's the 'flak' gunners on the seccondary weapons that do most of the sinkings.
3 - Edit your basic.cfg (info one or two pages back in this thread). As per
http://www.kbismarck.com/armament.html , Bismarck carries 1004 main gun shells, or 251 per turret - a far cry from the 120 that it comes with.

5 - Don't know. Radar usually works far better than my crew can see. If it's raining, and my guys can't see anything to shoot at until under 300m - patrols over. Check this program out, it's for GWX2.0, may work under 3.0
http://www.subsim.com/radioroom/down...do=file&id=424 - I can't alt-tab out of SH3 and back in again, it crashes. So I don't use it.
Hope I was of some help!
