Many thanks C_Calmes - AP is now working perfectly with ON1

[FastRawViewer]

I too have just discovered FastRawViewer - (through some very technical but really useful articles on photographylife.com) - FRV is brilliant - incredibly fast for checking your RAW images, with some great features (e.g. checking info in shadows and highlights) and the RAW histogram is a joy to behold (rather than relying on misleading in-camera histograms and if I might say so, the AP develop persona histogram) for those us of us newbies trying to get proficient with ETTR!!
