P: Mouse wheel changes brush size and scrolls image.

Thanks. I didn't see any version identifier in either of those locations, so I guess that meant I didn't have 2015.1 installed, even though CC said there were no updates available. I installed LR6 from the CC control panel and reinstalled and that pulled down the 2015.1 version. Thanks again!

When you launch LR, in the bottom left corner should say 2015.1 (if you're running the CC version which you say you are. Or, click "help" on the menu, then "About Photoshop Lightroom CC". At the top left under the word "Adobe" is should say "2015.1 release"

I still see this issue in my LR 6 CC. The CC app says I'm up to date with the latest version - is there a more definitive way to verify that I have 2015.1?

Thanks. Cc/2015.1 seems to have fixed this.

...and if you try to change the feather (shift + mouse wheel), the image scrolls vertically. At least the bug is consistent 😉

If you want to use the erase brush while you are working with the gradient filter and you use the scroll wheel of your mouse, you will notice that not only the brush size changes (as expected) but also the picture is moving up or down. This is the case if you have enlarged your picture 1:1 by pressing space bar.

In Develop module, after drawing a Radial filter and then zooming in to 1:1 or 2:1 and invoking a brush with key to paint out some of the radial oval, the scroll wheel on the mouse moves both the image window as well as adjusting the brush size. In this context it should only adjust the brush size and not move the window.

When using the Graduated filter or Radial filter and zoomed in with the Navigator in the new BRUSH mode, changing the brush size with the mouse wheel causes the screen to scroll wildly as well as changes the brush size.

In LR CC, now we finally have the brush in the graduated/radial filters. And, same as in the adjustment brush, we can use the mouse wheel to change size, which comes in very handy.

But when using the new brush inside the graduated radial filters, the mouse wheel not only changes brush size, but also scrolls the image, which makes it for an extremely confusing experience. Scrolling through the image using the mouse wheel should be disabled while in this mode, as it is when using the "regular" adjustment brush.

(Note: You have to be zoomed in to check it, if image is fit to screen, there's no possible scroll)
