When you click on Radial filter and click on the image the small part of image goes red and local adjustment sliders do not work. Only when you click done do you see any change to the image. The same goes for the Graduated Filter, can anyone help.
Sorry for the delay in responding. I have Photoshop Lightroom CC 2015.5 release (camera raw 9.5) and my Mac is OS X EL Capitan version 10.11.6. (2012). Please find enclosed screen shots of grad.filter and redial filter. As stated the adjustment sliders do not work when viewing the images I want to work on but you only see the different adjustment when you click done . Let me know if you need further info. Many Thanks Alex.
Thanks for the info but still did not clear the problem. I have taken Adobe advise and if all else fails clear all preferences and start again. Guess what, it has worked and I have opened Scott Kelby's Lightroom book and working my way to setting things up again. ( after having a few large drinks) Many Thanks Alex.
