Strange ATV2 behaviour - Movies can't be selected for downloaded & most menu items not selectable??

Question

ATV2 fully online, previews movies, downloads YouTube, Homesharing all good (and a seasoned ATV owner and user)
However download movies is not working, and no error message just a "beep" sound when you select "rent movie".
Also many of the menu items cannot be selected.  You cannot down select most of the items under General, so it's impossible to change settings, or to do any troubleshooting.  You get the same "beep" sound when you select Name, Network, iTunes Store, Reset, etc.
I have done the usual power down, plus reset using remote, but the system doesn't seem to go back to factory default.  I haven't tried the mini-USB connection to MAC as I don't have a cable but hoping someone can help?

Very puzzling that I have only seen the bad behavior on Win8.1, and not when debugging the extension.  (Haven't been able to try the extension on Win8, but have tried it on several Win7 computers, and one WinServer 2012 R2 computer.)
Is there someplace to look for runtime exceptions?  I haven't seen any in the Output window when the bad behavior occurs....
(If you want to try the extension, you can add a gallery and point it to www.cbates.net/VSIX/atom.xml.)
