I can be typing along in my document when all of a sudden, the cursor is no
longer on the line and nothing I have typed from that point appears. I have
to put my cursor back at the point it quit to continue to type. I can only
type two or three words before it does it again. If I am not typing, this
doesn't happen and the cursor stays blinking at the end of the line where I
put it.

I see a slight blip when this happens and the cursor disappears, almost as
if some other function is happening at the same time. I have checked my auto
save, but it is set for 10 minutes. This happens every 10 - 20 seconds.
