My sorter has been playing peek-a-boo. It slides in and mostly out of view unbidden, to the point where I can’t use it. Anyone else having this problem?

This has been mentioned in a number of threads. One culprit has been KeyCue. When the sorter tab disappears, just press the command key until KeyCue comes up. Then the tab returns. If you don’t have KeyCue, then some other app is conflicting with the sorter’s tab.

Thanks. I rebooted, and that seems to have resolved the issue, at least for the time being.
