I know nothing, but

In fact, you must register a display callback via glutDisplayFunc() before you enter glutMainLoop().

Well you must know something because I think you're right. I reconstructed the demo and this is what I get when I run it: 

freeglut (C:\Euphoria\bin\eui.exe): ERROR:  No display callback registered for window 1

Edit: Assigning an empty callback via glutDisplayFunc() makes the window open correctly. Make sure you are testing these things with eui and not euiw so you don't miss out on any console-printed error messages.
