Since downloading the free Edinburgh, I've just gone and purchased your VFR Airfields. It actually arrived before the VFR scenery for the same area. I'm still awaiting that. But, I'm impatient, so I loaded it up anyway. First airfield that I tried was Bristol, and, "Hey Presto", more black polygons. I was mightily miffed.....
Anyhow, upon checking back to these forums and seeing that you had replied, I decided to take your advise and update my g/c drivers. Re-ran Edinburgh (and Bristol), and result!!
Black poly(gone) now. I'm a happy beaver. And am also well pleased with the VFR Airfields pack. Fantastic value for money.
So, apologies all round, and I guess I'll update my drivers BEFORE seeking assistance in future. I'm such a dipstick at times
All the best, Andy
