I just got my X with froyo and was using the stock home screen. Then, I downloaded ADW launcher. When I pressed the home button to back out of the market, my home program was ADW. With my droid 1 you had to select which home program to use and select it as your default. This option never appeared with my X. Also, I tried going into the applications menu to clear defaults but none were shown for ADW. I uninstalled ADW and the stock home program was there again. Thanks.
