Has anyone else run into an issue with touch elements (e.g., app listings following a search in the Store) not responding to touch? I am, I think since the July firmware updates (but I can't be certain about that). For example, right now I can't click on the apps in the Store showing up from a search, even though touch is working elsewhere in the system. I think this is a software issue and not hardware, because I can't click on those elements even with the touchpad. Whatever it is, the only resolution is to reboot.
