When I click the home button (the haptic button to the bottom left) instead of going to my home screen, a window pops up with two options, HTC sense and launcher. HTC sense brings up the sense UI, and launcher brings up stock Android OS. I don't recall changing any options. Usually when I tap the home button it brings me straight to my sense home screen. No urgency , I'm just trying to figure out how it changed like this. Thanks in advanced.
