Just for everyone's info- there appears to be something glitchy with Sleep mode in Win10 (glitches in Windows? nooooo!) that can, in certain circumstances, muck up the Chrome/new Tampermonkey combination. If you start getting Tampermonkey errors when you open the browser, and/or it shows no script installed on the site, try rebooting. Not sure where the issue lies, though it only appeared with the latest TM update.
Sleep mode on Win10 is, in fact, a trashfire. But that's another discussion.
