can't enter any menu

 I have Recalbox running on a Pi 3B+ with composite on a Sony 4:3 480i CRT TV. 
 I also have a wireless keyboard/trackball (Banalove) and a controller (Thrustmaster T-mini).
 When I press enter on the keyboard immediately at boot time, the "MAIN MENU" comes up. I can use arrow keys to scroll up and down. But if I press ENTER again, the main menu just disappears. As such I'm not able to select any option of the menu.
 I don't see a mouse pointer either, though it seems the mouse is actually active.
 Is anyone else seeing these issues ? I'm pretty much stuck with Recalbox because of it at the moment.

 @madbrain I connected the Pi 3B+ to a KVM and a regular 1080p monitor. An overscan problem on my CRT was hiding the instructions at the bottom on how to enter the menu. I was able to do so with the mouse buttons (even though there is no pointer). And then subsequently I configured the Thrustmaster controller properly. The Pi is back on the CRT now. Unfortunately, the overscan problem is back, too.
