Sentiment Analysis Freeze

I like to edit with the sentiment analysis on but it tends to freeze at odd times. Sometimes a few minutes after I turn it on, other times I can go twenty minutes before it freezes but it always happens. Anyone else have this problem?

Once I turn it off, everything goes back to normal so it’s more an annoyance than anything, but I’m doing so much editing it’s getting to me. Any ideas of what I might be doing that is causing it to freeze are appreciated.
