Oh well - I should hvae listened to my own advice and waited for an official statement of support or release of new version. I installed v2.1 under OS 10.3 and all I got was a continually respawning Dock and Menu bar, had to use fast user switching to log onto another user name to restart the system in order to clear it. - only rating this post as not recommend for 10.3 - I used it for a long time under 10.2.x without problem.
