dgsmonX 0.2.1 is out already. This release addresses a compatibility issue with the previous release 0.2 (made one week ago) which made it impossible to launch the application on Mac OS X 10.5 and earlier. The new release should now work correctly on 10.5, but unfortunately support for Mac OS X 10.4 had to be dropped. Get the new version from the project page.
