If it's really important to get into those guns, I use the 5 and 0 keys to angle my view down then select the guns.
I just noticed offline on one of my terrains that the task force once again is not showing up on the chalk board like they used to. The rule for task groups is to set them and leave them at their default pointing north position, then add way points. If you changed the task group object's compass orientation manually in the terrain editor, the task group would be jumbled around on the chalk board with some guns unavailable below the edge and ships sitting on each other. All of my task groups point north and are now strung out vertical with two destroyers below and off the chalk board.
