I am pretty sure this is not relevant to your specific problem but as  
far as I can tell none of the easygui examples worked for me in 1.3r1  
because of the ns-string issue (Lisp string no longer being converted  
automatically in NSString. Trivial problem to fix but strange to find  
that the example folder had not been updated as part of the release.

We did update the Lisp User Interface (LUI) to work with 1.3. I will  
post at some time
