It isn't easy to summarize the problem in the title. So in 1.5 or 2.1 v1 or v2, it was very rare for the Sense UI Home app to have to re-launch. By this I mean when you click the home or back button to return to your Home screen, instead of seeing the home screen you see the black screen with HTC on it, then you wait while it loads the Home application. This very rarley happened before v1.3. Now it seems to happen at least once or twice a day. I don't have more apps installed than I did before, I shouldn't be any more out of memery than I was before. I can not identify aggravating or alleviating factors. Thoughts?
