Open the Tool Presets window. Now click on a preset. It should be highlighted now.
Next, re-size the brush (up or down, doesn't matter).
The highlighting in the Tool Presets window is now gone. Now we can't keep track of which preset we're on. I have 1000's of presets, and sometimes I like to browse through them and test them out. It's impossible to keep track of which one I'm on if the highlighting keeps disappearing every time we re-size the brush.
Would Adobe be able to look at this?
