Lightroom Panels Close Randomly

[photo-Mikey]

1.   Since the previous update, as I work in Lightroom, all panels, left and right, top and bottom, will disappear leaving black and blank space entirely around the photo I am working on, which remains.

There is no way to correct this except to close and re-open Lightroom.

Any idea why this is occurring?

2. Every time I select edit in Photoshop as Smart Object, I receive a message that I must update to the newest Camera Raw, which I already have.

Andy idea why this nuisance?

Thanks for any ideas
