Ghost ships?

[slammer]

I recently installed RUB1.45. I have "gods eye view" enabled.
When I first look at the Nav map I see ship icons as expected.
When I zoom in and am able to see the bearing overlay I see
a small mark where an enemy ship is located which is fine.
However I also see small marks for this ship every few km's
in a straight line leading away from the ship almost looking like
its plotting the ships course! I also do not see any hydrophone
lines at any time. Also if there are multiple contacts every contact will
have the same behavior as decribed above. I re-installed with a clean
sh3 copy with the same results. Am I screwing up the install or perhaps
missing some config I should set? Ideas? Thanks.
