Thanks for the reply.

I did have a mail rule set to trigger when I received an email with +omnifocus in the name. But I don't think it was the cause since I haven't run Apple's Mail app in months, and neither have I sent myself any such emails. Regardless, I've disabled that rule.

I also have no cron jobs or iCal events set run scripts, and I only have one instance of OmniFocus installed. Odd.

I appreciate your suggestions. Let me know if anything else occurs to you.
