Thanks to both of you for your input. I updated Chrome with no change, but when I took GabeU’s suggestion and checked my extensions I found the problem! Turns out it was Adblock Plus. When I turned off blocking ads on the Community website I was able to reply to posts using Chrome. I searched the AdBlock Plus release schedule and found the current version 3.14 was released on May 27, and the end of May was when I first noticed this problem. After many years this is the first time I have had any issues with Adblock Plus. Thanks again for your help.
