So, believe it or not (I'm not sure I do), I'm getting the same behavior in SLIME - if I run (test-g:gtk-demo) from the REPL, all is fine; if I evaluate it in the editor, the window never comes up and the modeline says "eval...". I also just tried the latest CVS, to no avail. Still no problems with SBCL.

I've had problems getting cells-gtk to play fair with the lispworks editor -- the whole #+lispworks thing in gtk-app.lisp we talked about -- but nothing like what you are describing. Does the editor have an event loop in which you could add a hook to run something? (I don't know what, cells-gtk? diagnositics? But it might be something to tinker with). So in summary, it looks like cells-gtk is OK on LW 5 (this is linux, right?) except for interaction with LW's editor. It's probably OK in slime, for example.
