I would like to add to this - I am using a wacom primarily for RSI and ergo reasons - I find little things in the editor don’t work with wacom pens - such as Content Browser - click on a browser tree arrow/triangle with a wacom and it does nothing, click on the same arrow with a normal pen and it expands the children. This means I have to keep switching to a mouse to do something basic that should just work. I prefer not using the mouse because it hurts.
I can see when I use the Wacom that the click is showing up as the triangle turns black - but the tree does not expand. Using the mouse the same behavior with the triangle turning black is registered, but the tree is expanded.
