I'm running FSX on Vista. Installing add-on aircraft is easy and they fly fine, but their photos don't show up in the 'Select Aircraft' menu. I see some designers add a thumbnail and some don't. I see the FSX default aircraft have thumbnails in their 'Texture' folders and those aircraft show up on the 'Select Aircraft' menu just fine, as one would expect. I've tried adding the add-on designer's thumbnails to their 'texture' files, but they still don't show up in the 'select aircraft' menu. A basic newbie question for sure, I realize, but how do I get these add-on aircraft to show up in the 'select aircraft' menu?
