I have a default set of tabs across 2 Explorer Panels, all of which are Locked - Allow Subpath change.
But since installing build 2242, I get an entry in the log at startup, such as:
"2016-08-11 15:48:55.745 [3012] Cannot lock path. Path don't exists : REG:\"
I am able to set the tab to "Lock Tab - Allow subpath change"
