Photoshop CC 2015 not responding to single clicks/small strokes on Windows (Lazy Nezumi bug)

Alright, I've been looking for a solution to this but I can't come up with a good way to word what the problem is in a search, so here:

I've been using Photoshop CS4 for the past several years, and figure it's about time to upgrade, so I downloaded the trial of CC 2015. It's functional for the most part, but it doesn't seem to respond to single clicks with really any tool--I need to drag to select with the magic wand and such, which makes it really hard to get into small areas. It also doesn't seem to want to let me paint in small strokes; I get this little loading circle that just kind of sticks on the screen and stays there overtop of any application I have up until I click and hold somewhere else:



The whole thing makes working on small details of any kind nearly impossible. The cursor also occasionally "sticks", and instead of ending the brush stroke/selection/whatever when I pick up the tip of the tablet pen, it just keeps going until I click somewhere else.

Again, I'm using Photoshop CC 2015, on Windows 10 (64 bit) with a Wacom Intuos Pro. Lazy Nezumi Pro is also installed, with the default settings. All software and drivers are up to date, as far as I know. I get none of these issues when running CS4 on the same machine with the same equipment.

Other users are not having this problem, so it is something about the drivers or configuration on your system.

Try disabling Lazy Nezumi. I think they had a problem similar to this a while back, so you may also want to update it.

For some reason disabling LN was the one solution I didn't think to try; doing that seems to fix the issue, but ultimately doesn't do me much good since I now have no line stabilizer. LN is up to date and still works fine in CS4 though, so it has to be some weird compatibility thing with CC + my computer. I can't seem to find anyone else having this issue either so who knows.

Oh well. Guess I can always go back to CS4.

Thank you anyway!

Then you need to contact the makers of Lazy Nezumi and see if they know about this bug and have an ETA for a fix.

Hi Liz,

Please go to the control panel's "Pen and Touch" settings, and disable the "Press and hold - right click" option.

This setting can interfere with Lazy Nezumi in Photoshop.
