Sometimes, when I switch to the explorer view to change extents or accidentally click it, I cannot click out of the explorer view, unless I scroll the view, then I can exit out of the view. This does not seem to happen 100% of the time, however.
I wonder if this might be related to a general bug that I run into myself but still haven’t quite tracked down, where WM loses track of what viewport has the active focus, and the usual F5-F9 keys or viewport commands stop working. Usually clicking in the viewport and trying again fixes it. That bug can occur for any viewport.
I’ve determined at least one root cause of the issue I described above.
If you click on a clickbox or slider in the layout view, the viewport focus is not detected correctly and you can’t switch to a different viewport with the hotkeys. Other widgets (including editboxes, buttons) do not block focus detection.
I suspect there is some similar but more obscure interaction causing the explorer view stickiness you described above.
