TimeCopy Conduit is now being supported by Scott Gruby. He graciously offered to do the OS X work and it turns out that he is much better positioned to maintain the non-Carbon version as well. Thanks, Scott!
Please see Scott's site for all Mac-related TimeCopy files and information.
The last remaining bug, where the Conduit Settings window erroneously displayed a set of options when the only available one is to have the Macintosh overwrite the Palm's time, was also fixed by Scott.
As a final note, I'd like to thank all the folks that showed an interest in TimeCopy Conduit, especially those that took the time to report problems and help me resolve them.
