This is a quick fix to DoTimer to clean up the bugs in 5.04. I coded this for a guildmate, and he asked me to publish it.
Once the author of DoTimer updates his addon, I'll pull this one down. I can't guarantee it works 100%, but it does work.
5.1: Uploaded a new version, it works for me, but that's not saying much. If people could try it out and see if it's working, and report back any bugs, I'd appreciate it.
