Tweetdeck notifications

Problem: the TweetDeck extension for Chrome suddenly stops popping up notifications

Cause: the browser has updated and now has enabled the "Rich Notifications" flag, which the TweetDeck extension can't yet use

Solution: 
1) Type chrome://flags into your address bar on Chrome
2) Scroll down to Enable Rich Notifications and set it "Disabled"
3) Scroll to bottom where it says to relaunch chrome to save changes and relaunch.
