V. 23.3.2 Masking Brush Doesn't switch to remove
I musta hit a key combination I'm not aware of or something.
Symptom: Using a simple layer mask, two layers X change foreground and background to black and white as normal. Black works fine, when switching "X" or using the little arrows on the toolbar, the colors switch but the brush doesn't change. It won't conceal again. However, if I switch the brush tool to the "Pencil" tool it works fine. I've checked all the normal things, nothing is locked, I've been using PS for decades, so I've done this masking thing many times. I must have switched something, any thoughts?
Thanks
