Hi All - I am having a very strange issue with mac mail. When I compose an email, and I go to edit it (delete some words or spell correct what I have typed) my cursor will delete full words or components of words in arbitrary locations in my body copy. I am guessing that this is some sort of font corruption but when I go to verify my fonts, everything passes the tests. Does anybody have any idea what might be causing this or how to remedy it?
I am going to try to clean out my caches and see if that works but thus far nothing has remedied the issue. I am running mavericks - the latest OS on a macbook pro 15" with retina display.

Thank you -
