I have a problem with my tablet and Photoshop. I'm using a Huion H610 Pro graphics tablet (because Wacom is too expensive ok). It works perfectly fine, and has been for 2 years. Just until recently that when I use it on Photoshop only, the cursor is all messed up. When I hover over the layers tab, it drags it instead of selecting it. When I use the brush tool, it just doesn't even draw. It drags the canvas everywhere when I click on it. The buttons on my tablet seem to work, its just the cursor and clicking with it.
Caps lock is off too. Always.
Please search before posting. This has been answered many times in the last few days.
The latest Microsoft Windows update (KB4093112) has caused an issue with tablets and Photoshop.
You can either - undo the update
Do the following :
1. Use notepad to create a text file and type in :
2. Save the file as PSUserConfig.txt in the following location
C: > Users > Username > AppData > Roaming > Adobe > Adobe Photoshop CC 2018 > Adobe Photoshop CC 2018 Settings
3. Go to the tablet properties and uncheck "Use Windows Ink"
4. Restart Photoshop
That is it - all should now work well (you need to do all the above steps to retain pen pressure)
There is a third option if the above does not work on your tablet. Microsoft made this change intentionally and they have issued a way round it with registry change (see link below). However for Photoshop and most tablets the PSUserConfig method works.
