It seems I can not currently select a resource inside the pop up selection windows with my tablet pen. Any time a double click is required in those pop up windows where you can select a resource, I need to switch to mouse to be able to select it. The tablet pen click does not seem to work there.
I have no problems in other areas of the program using tablet pen click.
Please see this voiced video for a demonstration of what I mean:
Thank you. I just experienced the same behavior when I want to double click to rename a layer in the layer Stack as well. It seems there is some double click threshold/interval problem or something in general in MAT when working with a pen to select things.
Tablet is my bread and butter. I work with pen in Unity, Unreal, 3D Coat, Blender,… basically everywhere, but I only experience this behavior in MAT.
I noticed that it can work when I click in a very particular rythm, a bit slower than usual. Then it seems to work. However, when the interval is too slow, it also does not work. Basically it feels like a sort of random hit or miss with pen. With Mouse, non of these problems seem to exist.
