Intuos5 (medium) and Lightroom 4 issue.

I'm curious if anyone else is using this combination. I just picked up the Intuos5 on Monday and have been using it with LR4 with great results. I love the customization of the tablet and pen, and it's really helping my workflow.

I have one of the tablet quick keys set to "ALT", so when I'm using my adjustment brush, I can just hold that button and use the erase brush, nice and quickly. I also have the touch ring set to do brush size. But when I press the quick key for "ALT" OR use the ALT key on the keyboard, and use the touch ring to do brush size (for the eraser brush) it does not work, it just flashes at me. The only way for me to change the eraser brush size is by dragging the brush size slider for it. Pretty annoying. Anyone else running into this?

I have an intuos 3 and about the same configuration. Works for me.

Maybe update the drivers?

Already using the newest drivers, thanks though Rene. Very confusing Small issue, but still an issue, ya know?

Do you happen to have a mouse with a scroll wheel? Does that work (both without and while pressing Alt)?

Might give a clue as to where the issue lies…

I do have a mouse with a scroll wheel, and that works with ALT just fine. But since getting the Intuos5 Touch, I no longer want to use a mouse

Weird.
Wacom prefs like this? ("Scroll" works as well)

Intuos5 doesn't have touch strips, but it does have the dial. I'll see what I can do with the scroll. Thanks for the tip.

On a strange side-note, my Intuos5 just defaulted back to its out-of-the-box settings... all my program definitions were gone, and now I have to re-setup everything.
