Hint: I had tweaked my filter settings but something, perhaps a driver update, lost them. I did some digging around and the settings are stored in a most peculiar/horrible way and cannot be backed up (trying to find the file(s)* being alltered was a game in itself!) - so when you’re happy with your tweaking make a note of them!
(*I think the settings are ‘stored’ in this file on my PC - C:\Users\paul2\AppData\Local\NVIDIA Corporation\NVIDIA Share\CefCache\Local Storage\leveldb\000063.ldb)
