Mozy for mac problems

Is anyone out there using Mozy for mac experiencing problems configuring the backup settings? I used to use this on my PC, and it seemed like a decent program. But I just downloaded it for my mac, and when I select "configure mozy," no dialogue box appears. If I select "start backup," it starts all right, but it want to back up my entire hard drive. Must be a glitch in the software. I've tried restarting and re-installing the most current version, but the problem persists.

Thanks!
