I have an intel mac with leopard. I downloaded and installed. I right click on a phone number and select Dial by Modem and it freezes. There is no way to remove it from the screen except by rebooting. I would reboot, find a name, right click on a number and boom...does it each time. I did set up my USB modem but even if i did that incorrectly, doesn't seem like it should just freeze.

Great Idea, love that people are having such success with it.
