Looks like event handling is working fine but for some reason window  
update is not working. Just to be sure try to upgrade to the cvs head  
version. (Note: Colors are handled a bit differently in the latest  
version; instead of (clear-screen 255 255 255) you should use  
(clear-screen (color 255 255 255)). But some functions still take separate  
rgba values, it is a bit messy atm...)

I'll see if I can get it working on my own xming setup.

That should work just fine.
