FYI, I talked to Melanie from Logitech Tech Support (Refence# 110805-001827) on the issue of "PageUp/PageDown" not working seems to be an known issue and they have had many calls on the matter. It apparently became an issue shortly after the b54202 update, so if you haven't configured your system prior to it then those keys have been rendered inoperable. Their developmental support is currently working to resolve it. In regards to the "Cancel" command, and after two seperate calls which took approximately 55 minutes in total, she said, "This appears to be a new problem. The cancel button is supposed to work as the ESC/Exit function" then she went on to tell me about the work around which involves using the "GTVBack" command for Google TV related menus and to use OEM Remote IR for the STB menus. Hopefully, they will get this feature fixed in a future update. It was explained to me that was imparitive that when I get the customer service survey that I notate it in the feedback and send it back. The feedback is submitted directly to her manager who then escalate the issue to development. Now, in my experience this is true; however, in order for it to have any priority it requires enough numbers to raise a fuss. So, I recommend that anyone and everyone who cares about this functionality to call Logtiech Technical support and make sure you troubleshoot the inability to use the "cancel" command to "exit" out of your guide in LiveTV and "esc" out any Google TV related menu. Allow them to give you the workaround, but make sure you ask them exactly what "Cancel" button is supposed to do from the MyHarmony for the Logitech Revue. It may take them a while to give you an answer, but at least when they come back to give you the answer where they will acknowledge that "Cancel" should be functioning as "Esc/Exit". Fill out the feedback, input the issue, and hopefully together we can raise enough fuss to resolve the issue.
