I am new but did manage to find this place about the same time as the leaked 2.1 came out, so of course I had to have it.
Anyway, aside from a few lags here and there I am ok with 2.1 but something strange happened yesterday after I installed Helix Launcher. After not being able to see the Helix app icon anywhere on my phone, each time I would hit the Home button, I would get a menu with 3 choices: Helix, Home and HTC Sense. Even if I chose Helix I really saw no difference in anything and/or couldn't find any new settings to make my desktop different like many talked about. Since I really couldn't find how to access Helix and use it, I went back to the Market and uninstalled it because it did not show up in my uninstaller app.
Anyway, since the Helix uninstall every time I hit the Home button I still get a menu: Home and HTC Sense. I have tried each and if I select Home it takes me to the UI that was there before I upgraded to 2.1. If I choose HTC Sense it takes me to the new UI and menus.
My question is......why would this be happening and specifically why after installing Helix? Maybe I don't understand what Helix really was but it seems that I have the option of using my 1.5 or my 2.1 UI now which I never had before. I don't want to select "Always choose this option" on either one because I wouldn't be able to choose any longer but on the other hand to get this menu EVERY time I hit Home is kind of a pain in the a55.
Any input on this would be great, as I said I am just now learning the Android.
