In Blender 3.5 I made B the brush shortcut in Grease Pencil Draw mode, when I updated to Blender 4.0 the shortcut no longer works and starts a 'box selection' operation. The E shortcut for the eraser tool still works, though.
So far I've tried reinstalling, resetting all configurations and (obviously) tried re-binding the shortcut.
Anyone else getting this problem?
