It took me several hours to track this down because the problem was not 
actually in the code changes I made, but the change exposed a bug in the low 
level polling for windows messages.  The low level code was not returning YES 
as it should when an event had been received/handled, so the higher level code 
depending on that return value was not working properly.  This should be fixed 
in trunk (works for me).
