My longtime tech buddy Chuck Shotton urged me to install the Canary version of Google Chrome, in the hope that the clipboard and debugger would work properly in this version.

Sorry to report, the clipboard is broken in the same way it is in the 32-bit version, and the debugger is worse. I can't get it to set a breakpoint in the proper place, and when it stops, it doesn't stop anywhere near where I managed to set it. I'm debugging the way I used to debug 35 years ago, with printf statements (it's called console.log in JavaScript).

Not that the other browsers are more reliable.
