HTC Eris :: Autoscrolling Issues Even When Not Plugged In

I've had my Eris for almost a year now. Like most of you, it was great until the upgrade to 2.1. Since then, I've been disappointed but it's been managable. However recently, it's gotten worse. I too am experiencing the autoscrolling issue when my phone is plugged in. I really don't have the time to go and haggle in a Verizon store about it, so I've just been dealing with it and not trying to do anything while my phone is plugged in.

Now, it's autoscrolling even when it's NOT plugged in. Half the time I can't type because it scrolls back, and I end up typing things backwards. I can't open apps because it automatically will select things or scroll to the farthest left screen. What gives?

Also, my texting has been freezing and force closing a lot lately. I will repeatedly close and reopen Messaging, but I still cannot send a text. I've also had a problem with other people not receiving texts that my phone says have been sent.

I also recently got a message that my phone internal storage is reaching capacity. I don't have many apps installed, but I went though and cleaned up anyway. I'm guessing one culprit is my texts, because I've deleted very few of any texts I've sent for the life of the phone. I have tried going in and deleting one thread (the largest one, I figured it would be the quickest fix: it's over 2,000 messages), but it just causes my phone to freeze and won't delete it.
