Hello all, I have the following snippet of code that doesn't work as expected under SBCL 1.0.29, CFFI 0.10.5 and Windows 7. (let ((library (cffi:load-foreign-library "user32.dll"))) (cffi:foreign-funcall "GetDesktopWindow" :int) (cffi:close-foreign-library library))) I have also tested it under LispWorks and CCL - no issues. Could anybody suggest the workaround? Thanks, Serhiy Y
