Lightroom freezes up after changing folders in the Library and going to Develop

[dpollard50]

I recently upgraded one of my PCs from Lightroom 5.7 to CC 2015.10 and began using it without problems.  After a day or so I began having problems.  When I went to change folders by going from Develop to Library and changing the folder everything looked fine but when I then tried to switch to Develop, Lightroom would show a busy status and never come back.  I have let it go for 15 to 20 minutes with now help.  I have had to close Lightroom and restart it.  It will default back to the original folder.  The only way I can change folders is to go to Library, close Lightroom, open Lightroom and then switch to Develop.

Any ideas on what's going on.

Thanks,

Dennis Pollard
