Freezing after group mail intervals

I have been having an issue where the interval setting for group mail will not work. It will send out the initial batch then begin the countdown, but once the countdown hits 0 it simply freezes.

The delivery information stops at something like this:
[01] 5/29 12:06:25 ~ Stage 4 dispatch done
[01] 5/29 12:06:25 ~ Next Delivery in 00:00:05
..and the settings page looks like the following. I've blacked out personal information obviously, but I assure you that all SMTP information is correct. The emails send find, it's just that the program idles after each interval. I've tried a wide range of group sizes and interval lengths, it makes no difference.

Perhaps i'm just not understanding this feature correctly. Any advice?

Mailer version: 8.4.3-US Pro - Registered
Machine OS/speed: Mac OS 10.8.3 Mountain Lion/2.2Ghz
