Speeedbird 068,
just to prove my point I played with rwy.bgl and managed to solve our problem. If it didn't bother you that 4R in my version had new freq which would be 112,50 and is LOCDME than I can e-mail you new rwy.bgl file.
ILS leads you right down to the treeshold.
As I have no skills whatsoever in terms of programing that means that all "this is not possible" statements from different skilled programers are quite a bull*****

. For real this is just matter of their will.
I solved this problem in 3 hours.
I mights also go deeper and manage correct freq once.
Let me know if you wanted my rwy.bgl.
