P: Sliders Not Responding after 2015.1 update.

I'm also having the same issue, video for reference.

I have a Mac OS X Yosemite ( 10.10.3) - I am having the same issue with the sliders as everyone else.

I'm having this same problem in Lightroom CC after updating yesterday (4/7/15) it is incredibly frustrating and slows workflow down immensely. When you are using lightroom professionally to edit wedding photos at nearly a thousand a wedding it is extremely painful. Please adobe take note and fix this problem.
Thank you!

Same problem here. I had the Lightroom CC Trial before, and it worked fine. After the 2015 Update I subscribed to CC. Now I'm having this issue. It wasn't there before. If it had been, I would not have subscribed. Thinking about canceling my subscription while it's possible, if there isn't a fix soon.
Impossible to work on LR on a Trackpad this way.

I am having this issue as well, for me it happens when I click close to where the slider already is, while if I click farther from the slider the adjustment will be made. Now I am clicking and dragging to make adjustments.

Just discovered the same on my Mac. LR CC 9.1 and OSX 10.4
Never had the problem before upgrading

I have the same trouble with the sliders "sticking". Strange that this update wasn't fully tested before it's release. For now...it's back to earlier version.

Same with me - the upgrade in cc. Just to add my support to what's been discussed above.

While this is frustrating, the simplest workaround for now is to click and drag the slider knob. It's an extra step, but not that much slower than clicking at the intended setting on the slider bar.

Adding my voice to this. Incredibly frustrating to try and make small adjustments and much more time consuming.
