I was just wanted to use the Bevel Border. For me this means getting an ugly hard black line on one of the long edges. I never been able to remove this. So, a bit of lateral thinking on my behalf .. I just "chained" to border fxs - One is "Bevelled" and the other is "Blurred". Increased the size of the Blur border a smidgen, and bosh, nasty line gone!

Grazie
