I never used to have this problem, but somehow my settings got messed up. I have Launcher Pro set for 5 screens. Previously, when I was in an application and I hit the home button it would always take me to screen 3, which I had assigned in the settings. Now when I hit the home button, it takes me to whichever homescreen I was last on. I checked the settings and 3 is the default. What changed? How can I fix this? Thanks.
