So, when you upgrade to version 42 and then attempt to play a jigsaw puzzle you will see the page that says Silverlight needs to be installed to play the puzzle. If this happens to you, and you know Silverlight is already installed, then follow the Chrome version 42 instructions on the How to Ensure Silverlight is Enabled page to re-enable Silverlight.
