Out of curiosity, which version of Windows is this happening in?

Aside from that, seeing as my HDD where FSX for Win 7 is installed has gone AWOL, I had to test the 707 in FSX-SE. I'm not having any problem with a missing Glide Slope there. :-/

I haven't been able to try it in FSX for Win 10, as Win 10 itself is playing up, and it looks like I might need to reinstall/repair that. Seeing as I have bought 2 replacement HDD's, I don't really want to do all of that right now, and would prefer to wait until the HDD's arrive early next week. :(
