Toggle Course Line visibility

[DimSim]

Turning the Course Line on is fine, just hold or click the CRS switch. However, it seems to have a mind of its own after that.  Sometimes it disappears even though the active waypoint is visible on the EHSD map. Other times it can stay on forever and even appear twice or more, displaying on the active target point as well as previous waypoint.

Question is, without changing the course bearing, how can I toggle visibility of the course line on and off whenever I choose?

I too experienced the disappearing CRS line but didn't investigate. But this old thread seems to explain it. As I understand it now, first you need to be in the map scale that shows the TCN or WYPT symbol for which you set the CRS line. A TCN CRS line once set will always be visible if you are in the right map scale and have TCN button selected. However, when a CRS line is set on a WYPT, selecting another WYPT (W) or selecting TCN button causes the CRS line to disappear and the only way to get it back is to set it again. This doesn't feel right and I am not sure it happens this way in other jets.

Thanks. That's generally the case, where it's hidden when the active point itself is out of range. However, sometimes it seems to be gone when the active point is well within range. I'm mainly trying to find a way to intentionally hide it.

The course line does appear to have a mind of it's own when dropping the scale. Seems ok at 100nm, but anything less it seems to be unreliable or non existent even if the Tacan or Waypoint is visible on the map and you are well within range.
