I recently noticed this issue — when starting Photoshop and using the brush tool (90+% of what I do), the brush window shows the first or top brushes in the palette, not the currently or last used brush. If I try to change brushes via the ',' or '.' hotkeys, the window will not advance to display the current or last used brush (though the brush is changing). I have to scroll through the window itself to the brush I want, and select it in the window for the brush window to behave normally.
Is there a fix for this? Thank you.
