Apple Magic Mouse scrolling behaves poorly in Adobe apps

The custom mouse drivers in Lightroom, Photoshop, and Illustrator don't seem to support the Magic Mouse properly, even though all applications by other software companies work perfectly. The scrolling is not calibrated properly for the mouse. Anything with a scroll bar seems to scroll perfectly, but other scroll event cause unwanted side effects. For example, when I try to click to zoom on a photo in the display window, many times Lightroom detects a tiny scroll and zooms across tens of pictures in the navigation strip below. There are similar problems in the other Adobe applications, probably because of the proprietary mouse driver. Are there plans to fix this? I would love to be able to disable just the navigation scrolling when you are hovering over the big picture display, while keeping scrolling for the strip below.

Yes, the "magic" mouse gives some bizarre inputs compared to other mice and input devices.

Clicking the magic mouse frequently DOES scroll as well -- the OS sends both sets of events to the app, and the app cannot tell that you didn't intend to do both.

And no, there are no proprietary mouse drivers in Adobe apps. Plus most of the Adobe apps don't even share code. So what you're seeing are a bunch of independent applications treating the mouse the same way: reading the events exactly as the OS sends them. The application has no idea what kind of device it's receiving the events from (can't distinguish one mouse from another, and can only tell it's not a tablet because there are no pressure values).

The only parties that can see the details of what's happening with the mouse is the mouse itself and the OS. Any cleanup of the behavior would almost certainly have to happen in the OS code.
