Tower Views on FS9

First off thanks to all of you who design freeware, whether it be planes or airports, your efforts certainly have made my experience with FS9 and FS2000 so much worth while and a lot more enjoyable. You have taken an alright program to a different height and MS should be putting you all on the payroll.Now that I have said what I have wanted to say on here for a long time. It seems that no matter what I do either with afcad or using the map window on FS9 and manual moving the tower so that the Tower is in the same state as the airport nothing is saved and everytime I load up FS9 I have to do the same thing all over again. I thought afcad would fix this but it seems FS9 ignores where i put the tower on the airport bgl and reverts to the same old position at ground level at some default position. Is there any way to change this?Flying HighDon
