GMAT build that I'm using is: May 19th, 2014.
1) Please upload the script. Open 3 Orbit View resources (EarthView, SolarSystemView and MarsView) and notice that Solver Iterations is set to Current.
2) Now run the script. As the targeter is trying to converge onto a solution, you'll see GMAT draw current iterations in teal color which is set on Spacecraft resource using TargetColor field. This is correct behavior.
3) Now after about 3-4 iterations, the targeter will converge. After converge, the EarthView and SolarSystemView orbit view windows draw final converged orbit trajectory in Red, but the MarsView window does not draw final converged orbit trajectory in Red and still draws the final converged trajectory in teal color which is set on Spacecraft.TargetColor.
Since Spacecraft.OrbitColor is set to Red, Just like EarthView and SolarSystemView, the final converged trajectory in MarsView should have been drawn in Red color as well. This is the bug.
I have attached screenshot of this behavior. Notice that in MarsView, final converged trajectory is STILL drawn in teal instead of red.
