Let us know if that helps.
I tried unchecking the graphics processor first. Finally, I uninstalled Lightroom and rolled back to a prior update version(Lightroom 6). It seems to be working properly but now I am afraid to get anymore updates. There is a patch that goes along with it but since it's working properly and not hanging up when I click between the Develop module and the Library module, I think I'll wait to do anything more.
I do appreciate the timely response. I was not expecting that at all.
There will be changes in the next update for Lightroom, so you can wait till its out.
