hey mate, just signed up, wanted to metion that i've had this problem also, i have the ascend but i think its an earlier model but maybe this will also work for you.. if you hold down the the go back button (next to your home button) mine will bring up a screen with the 4 or 5 different home screens, at the bottom of each one is a little home button, find the one you had and change it like this.. also read that the reason why this is happening is because you may of run out of room for more apps / widges on your home screen, and is why it seems to change your home screen to a different one... hope this may help people out.
