Not sure where to post this, but I just received my new Wacom tablet and have been using it, but I have run into an issue. When in Photoshop and draw a line, I then go to continue that line with but my brush turns white instead of keeping black (despite claiming to be black on the color swatch) but when I try it on a blank section it is black. I like to work zoomed in so this happens often, does anybody know what is happening?
