The above demo contains an interface, but issues arise if you don't have one as well.

Without a defined interface, movement macros(arrow keys) aren't causing movement in the map, but are registering in the command box below the map. You can see that by pressing left or right. Pressing up or down moves the browser scroll bar up and down some.

The same issue occurs with movement if you have a custom interface, but at the same time none of the other macros you have defined call the associated procs or verbs. I tested this with NEStalgia and button presses seem to be affecting the browser in the area outside the game window.
