I suspect the problem is that you are not running GUI operations on the main thread which is a requirement for many Cocoa functions.
See run-on-main-thread function in examples/cocoa/easygui/new-cocoa-bindings.lisp.

It is a lovely explanation, just the sort of thing I was looking for. After just a few steps it ends with the promising claim that "The window, empty, but with the shape and features we specified, appears on the left lower corner of the screen”. Unfortunately, for me, with a freshly downloaded CCL and the Hemlock IDE, the window does not appear. The screenshot below shows me going through exactly the steps in the HowTo, with no window appearing. Any ideas about what has changed or how the HowTo should be amended?
