if you have tma autocrew on, he wont let you move the ruler.

are you hitting "enter" at the bottom of the top right window in TMA?

When you cross up those lob's, right click on the nav map and use "add manual solution". Classify the target and make it hostile so you can engage it for sure. Trying to do TMA after this point is only going to give course, and speed(because you already know the range and bearing). And you don't have any demon with a buoy. You're really not supposed use TMA for figure speed of a sub, thats what demon is for (demon can do it instantly, instead of having to wait 2 minutes...) Also, the buoy range is so limited compared to a sub, that by the time you did do TMA the target could be out of range. That sub isn't going anywhere soon. Your torp will starting homing around 1.5-2 miles so drop a "circle" torp.

if you want to anyways, you gotta pick the added manual solution in the tma with the other two LOB's visible, the move the manual solution.
