If you are using Lightroom CC 2015 or Lightroom 6, go to your Lightroom preferences, performance tab, and uncheck the GPU option. See if that makes a difference.
Thanks for the suggestion, I am talking with tech support and asked me to uninstall the program and re-install it. I meant to mention that this is after I upgraded to windows 10. If it still has the problem after I do the reinstall I will follow your lead. Thanks Jim
Ok after reinstalling Lightroom CC the tech took over the screen and did some magic including un-checking the gpu option. He also reset a couple of setting in the preferences. Now so far all is ok...Again thanks for the help..Have a great weekend
