How to lock a view?
The X1 manual says that you can lock a view by:
1) Clicking the "lock button" at the top right of the view
2) Clicking the upper left corner of a window and choosing "lock contents" from the pop-up menu
3) If the view is in the MultiDock, right click the view's tab and choose "lock contents."
However,
1) There is no "lock button"
2) The menu offers no such option
3) The tab's menu also offers no such option.
I feel like I'm going mad, looking for something that the manual describes which is completely non-existent. Does anyone else have this feature?
