Using SW2013 SP0. I have created an exploded view of an assembly and placed the exploded view in a drawing. The view in the drawing is at a custom view and not a preset view (like ISO, etc.). The drawing has a BOM already inserted. When I go to add balloons, either auto or manually, the balloons point to edges that don't exist. The arrows are always just a little off the true edge of the part, pointing at what it thinks is the edge, buts its just space. I have tried rebuilding, restarting SW, restarting the computer, and its still confused. Might this be a graphics thing? Or related to the fact that the exploded view isn't in a preset orientation?

Appreciate the help.
