Hi, 

You might have a look at start-app in root/cells-gtk/gtk-app.lisp. I coded the 
use of restarts in that code. Despite reading up abot restarts in Practical 
Common Lisp, I still don't think I quite understand them. So that code is 
suspect, especially because it has #+lispworks in it. Maybe you could try the 
code in start-app that currently is #-lispworks. It simply runs gtk-main. The 
idea of the the #+lispworks alternative (stuff with 
process-wait-with-timeout) is to give other processes (slime in particular) a 
chance to run.

I don't have LW 5.0 yet so I probably can't be much help.
