Droid 2 definitely has multitouch capability, however not all apps designed to show those individual touch points will work properly. If it didn't at least have the ability to distinguish 2 separate touch points, there would be no way to pinch to zoom. The Droid RAZR has 10 point multitouch but earlier technologies had less, initially only distinguishing 2 points, some have 4, others 5, etc.
As for "fixes", the only thing you need to do is find the right app that recognizes the multitouch properly.
I realize the Droid 2 has Multi Touch technology. I think you're misunderstanding what I'am talking about. My phone can register 2 touches at the same time and Pinch Zoom works, it's just when I'am tapping my screen with 2 fingers simultaneously is when it doesn't seem to work. For example I'am holding down my left finger and my right finger on the screen, both fingers are stationary but only one finger will register.
