I've had to uninstall and reinstall FSX and Horizon VFR Photo' Scenery Gen.X Version 2  Southern England.   I now find that the FSX default airfields do not blend with the photo' scenery but show 'cliffs' around some airfields. I do remember this feature way back when the scenery was introduced and it was subsequently corrected.  Could I have help with this feature?  I do have DVD discs for UK2000 Scenery Airfields - Southern England.  Would installing these help?  Thanks.

Problem solved - installed FSX Acceleration .
