I had the same ghosting issues with my A955 Droid 2, my problem area was the middle of the screen. I noticed that if I locked the screen, held down the ear-speaker area, unlocked, and kept it held down, I could use the touch screen no problem. Does that mean adhesive is part of the problem?
So, I tried a modified approach to the original poster. I got a baking pan and a dish towel, put the dish towel in the pan, and put the phone screen facing down on the dish towel. I "baked" it in a regular electric oven for 45 minutes at 170 degrees Fahrenheit and the touch screen worked fine for about 2 days.
I just did it again tonight except what I did differently was I did it for 80 minutes and I let it cool in the oven itself for 3 hours after instead of pulling it out and letting it cool outside. We'll see how long it lasts this time. But, thank you original poster for giving me a rather oddball way of dehydrating electronics!
