Just updated my Photoshop to Photoshop CC18 and now I am not able to define the size of my brush with my wacom pen. Using the right mouse key + ALT , it works as it is used to be but using the pen + ALT (using the button as right mouse key) I only can choose a colour. Can anyone help me ?
The alt right click issue has been fixed with Photoshop 19.1, so you do not have to use the PSUserConfig file to revert to WinTab. If you do use the WinTab fallback you need to make sure the file name is exactly "PSUserConfig.txt" and the file needs to be in the location specific to the version that you are running. (PSUserConfig in PS2017 location does not work for PS2018)
