Thanks for the additional info.
QAP is designed to open folder in a) the current tab or b) a new tab or lister.
a) QAP opens the folder in the current tab:
- when the mouse is over a lister when you open the QAP menu (as in your video capture);
- or when the option "the current Directory Opus tab" (top right section) is selected (your current situation).
b) QAP does NOT opens the folder in the current tab when you open the menu OUTSIDE of the DOpus lister. Then it can open the folder:
- in a new tab when the option "Use tab instead of opening in a new window" is NOT checked (default setting);
- in a new DOpus Lister window when the "Use tab..." option is checked.
To obtain the result you wish, select "a new Directory Opus tab" (default setting) AND open the menu outside of DOpus: on the task bar, the Desktop or on any other window.
