If the following setting is checked in preferences..
..what constitutes do something in it per the description in the Help file? Going to a folder and selecting a file within it does not add the folder to the recent list. To me, that is "doing something in it". Even if I rename the file the parent folder is not added to the list.
Double click has no effect on my system (W7, Opus 11.16.1). I also tried with a vanilla configuration in case there is something in my custom config. Same result. Double click has no effect on the recent list.
Further testing with a vanilla config demonstrates that if I enter a folder XXX and double click an item, XXX is not immediately added to the recent list. However, at some point later when I navigate away from folder XXX to folder YYY then XXX is added to the recent list so the logic appears to be "do something and then go somewhere else".
