When selecting quality when setting a recipe, the quality selection only activates on mouse up, but every other part of the menu activates on mouse down. I believe this is a bug and not intended because it is only the case for this one part of the UI.

To see this behaviour, place an assembler and then open it to select the recipe.
To demonstrate the mouse-down behaviour, click and hold on some item, then press enter to set the recipe: the recipe will be set.
To demonstrate the different behaviour with quality, select an item, then click and hold on a quality level at the bottom of the menu. This time when you press enter, the recipe uses the default quality, not the one you were clicking on.

Thanks for the report however in what way is this causing issues?

The game in the majority of GUI cases tries to react to events on key up, however for technical reasons that wasn’t viable for craft and inventory related actions (shift click and such). The fact that the quality picker works fine on key up meant it didn’t have to run on key down.

But where’s the actual issue that would warrant changing anything?

I would say maybe a quarter or half the time when I am trying to set a recipe or request for something with quality I end up setting it to normal by accident because I press enter (or e) while the mouse is still down. I have also seen this happen in videos on Youtube more than once.
