Huge blocky shadows

[Naismith]

Can anyone explain or give a fix for these huge shadows which appear at some (not all) airfields. As I gain altitude they disappear. I use FSX Accel with DX10 fixer.

I see these only if I have enabled the legacy (Fs9) shadows.
Have you?

Silly me how did that happen. Fixed thanks.
