I have the latest version on my Sprint Treo 650. I'm running OS X 10.3.6 and haved the Treo plugged directly into the USB port on my mac (no hub).

The card will mount, but any attempts to open folders, move or delete files results in a spinning beach ball. The only way to get control of the Mac or the Treo back is to hit disconnect on the Treo.

Softkick has been pretty slow with e-mail support. Any ideas you have are appreciated.
