While this is normal for uninstall (and then afterwards install optionally to notice it), I do not understand why this is the case for reinstall (and thus for Market updates as well).

For example, I would like to have a service running that...

However, I would ideally like to see the TextView scroll in a fashion similar to the IPhone/IPod touch where the...
