After the MR I noticed I was getting repeatedly reminded about missed calls. Every day, day after day, I was getting alerts about calls that I already acknowledged as "missed."

I figured out how to turn them off...Somehow, these missed phone calls were getting converted into "Tasks". I went into tasks and checked them all off as "done" and now they are gone. I also unchecked all the preferences--not sure if that helped the problem go away or not...
