Do you have a Wacom tablet? If so, try updating the driver.
No tablet. Just a mouse and keyboard.
Does your mouse work in other versions of Photoshop?
I am not sure. The only other place I have access to Photoshop is at work. Is it possible to still download trials for old versions of Photoshop? Is there some menu in Photoshop that lets you pick and choose input devices? Maybe Photoshop THINKS I have a stylus or something...
Did you make sure you have installed the latest version of logictech mouse device driver?
Never need mouse drivers at work (I just use the Windows generic HID drivers).
Just installed Logitech drivers. No difference. If it helps at all, the mouse works fine in Lightroom 3.6.
Is this a laptop? If yes, try turning off wireless support. (Do laptops have Flight Mode?) Do you have other wireless periferals plugged into a USB2 or USB3 socket like a keyboard or router, and if yes, are they also Logitech? I can't think why that would be Photoshop CC specific, but it might help to isolate the problem area.
Recent Logitech perifierals and Setpoint, allow you to use the same dongle for multiple Logitech devices (Unifying). Do you have that option and if so, are you using it?
Have a look at the mouse settings in the Control Panel > go to Setpoint (last tab), and click on Advanced settings. (a mouse icon with a +). If you have Application specific enabled, try turning it off. If that makes a difference, turn it back on, and click on Configure and add Photoshop CC
It's a desktop PC. I do have a unifying receiver but the mouse inputs themselves work outside of Photoshop (i.e. dragging, right clicking etc.). Don't have anything application specific in SetPoint (I just installed Setpoint) today.
I just tried the following (none of which helped):
- Reinstalled Photoshop and Creative Cloud
- Ran Photoshop as admin and turned off desktop composition.
- No other USB devices plugged in.
Do you have a cheap corded mouse you can try?
It was Synergy being installed. I found some forums complaining about this and checked my programs list and lo and behold, it was installed (must have installed it a while ago and forgot).
So even if you aren't actively using Synergy, just having it installed (maybe it has a service running) messes with Photoshop CC.
FYI: Applications that ARE ok that could be suspect of similar problems:
- Display Fusion
Thanks for taking the time everyone!
Thanks! I have this problem today and removing synergy fixed for me!
Thank you for hinting Synergy, it was indeed a problem!
Looks like you don't have to uninstall Synergy. I didn't even have to stop the service. I simply restarted the service and Photoshop started working correctly again.
