How to open a new folder of images?

[blackxacto]

Either I have forgotten how, or I cannot open a folder of images using XnViewMP.

1. Opened XnViewerMP 0.96.2 in Catalina 10.15.4 on a 19,1 iMac.
2. Selected Open, found the folder on the desktop in the window.
3. Tried to select All the files inside the folder. No Joy.
4. Double Clicked the folder in the window.

Nothing happens, Open is grayed out.

Do I need to turn on a setting?

I now see that if I click the circular green arrow in the top left corner of XnViewerMP that I can navigate to the folder and open its contents. Maybe I forgot this. I guess its the only way to navigate using XnViewerMP. I appreciate the application XnViewerMP. Want to continue to use it.
