I have just had several people on Windows test this. All of these people confirm the dialog appears. You are also the first person I have ever had mention this doesn't work in over a year of this being implemented, so I'm not really sure what's unique to your system to prevent it. Perhaps some kind of unique casing paths, or anything else I'm not considering. It would not shock me considering you're in tune enough to fixate on the profiler in X-Plane.
