I work in a environment with lots of interupts, and one of the features I really like with Billings is that when I get back to my computer it asks me what to do with the time when I (or at least my computer) was idle.

But there is a bug in this feature: Even if I do pause the timer before leaving the computer, Billings will anyhow be jumping in the dock when I get back, claiming that a timer was running and if I check the box it will deduct time that never was added.
