Closing to next AAM range

Closing to next AAM range would be a wonderful feature,
(See how happy I was when I stumbled into it: Tony's revamped Game Engine #25)
turns out it's in the GE, but it does not work consistently, could say as illusive as Bigfoot. (But I've seen it I swear! )

It happened just after I saved the attached file:

• I press [F1] Attack for DRA
• Target list pops up with TRA preselected
• and a soon as I accept TRA pressing OK,
  • before or simultaneously to the Weapon Selection popup opening
  • (turns out TRA is within Sparrow range despite it being displayed outside of the range ring, so I get the popup)
• the message "Closing to next AAM range" is displayed in the log window
• and a course is plotted for DRA for a Python range intercept
• the Weapon selection popup is still open at this time

So it happened two times for me in quick succession but now I can't reproduce even with this lucky 1 second save file.

Pretty please, make this work!
