I just downloaded the new version of SubEthaEdit.

Before I installed it I Rendezvous'd the file over to my other Mac (which is still running Jaguar).

On the Jaguar machine, the contents of the disk image were copied to the desktop, and the image was unmounted automatically. On Panther, the disk image was mounted but nothing else happened... so it looks like Internet-Enabled Disk Images have finally bit the dust. I'm glad that disk image handling is consistent again.

Michael Tsai noticed this too. Good. :-)
