I'm beginning to fall in love with this library. Thanks so much. I am using Allegro modern lisp and there are two small issues that I've encountered.

(defun error-popup (message title icon &key (allow-yesno-p t)) (ecase (message-box message title (if (and allow-yesno-p (find-restart 'continue)) "yesno" "ok") icon) (:YES (continue)) ((:ok :NO) (abort))))

(defun debug-popup (condition title) (ecase (message-box (format nil "~A~%~%Do you wish to invoke the debugger?" condition) title "yesno" "question") (:YES (cond (*debugger-hook* (let ((hook *debugger-hook*) (*debugger-hook* nil)) (funcall hook condition hook))) (t (invoke-debugger condition)))) (:NO (abort))))

The keywords :YES and :NO used to be lower case and the message box is returning them as capitols. Only an issue because modern cares about case sensitive. I made the simple change locally and it works, but I thought I would pass it on.
