Folders keep auto collapsing in middle of working

[TREI 1]

I'm moving folders from external to internal and have to keep expanding the Folders to drag and drop. They keep collapsing/closing randomly/frequently and selecting Option and the trinagle doesn't lock them expanded like I would prefer they stay.

First, restart your computer. If the problem persists, try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.
