Panels disappear

[Richard2138]

While reviewing some folders and collections, the left and right panels disappeared and were replaced by large black spaces.  I've reviewed the tools and commands, but no luck.  Any way of restoring them?

This is a known bug in LR 6.8/LR CC 2015.8.

Roll back your LR to version 6.7/CC 2015.7

Hope the bug is fixed soon, the new feature in the Development Module that lets you have a reference photo to compare is really great.
