Have tried everything in this post and none have worked for very long.
I am going to try seeing if the Estrongs "Suite" is installed and causing a problem, but I definitely know this isn't a launcher problem as this happens with several different launchers...I thought it was a HTC Sense issue, but I have now seen (I think) a couple of posts from a Samsung device.
I have the Thunderbolt and since the 2.3.4 update, I have had the same problem. I have read several posts, but no real solution. The Homesmack didn't work. This Really sounds like an HTC issue, but I am still trying to read more posts.
