I just discovered this option in Directory Opus! It will interest DOpus users who like the dual-folder display (left/right or top/left or source/destination). Let's use the "source/destination" nomenclature here.
If it happens, for example, that you open the QAP menu on the "source" side, select a folder to change the location on the "source" tab and, as result, you see the folder location changed in the "destination" tab, this is because the "source" tab where you open the menu was not active. The folder was changed on the active tab, the "destination" tab.
In order to make sure that the tab where where you open the menu (the tab where you want to change the location) is active, enable this option in Preferences. Adjust the delay if required. The default value of 1000 ms was too long in my case. It has to be shorter than the time between when you hover the tab and when you open the QAP menu. In my case, 200 ms works well.
