I'm also running this application on a 10.5.8 desktop iMac.
I know how to create a brush (create image, have a transparent background, convert to "Grayscale," save with gbr {am I forgetting anything}) but the grayscale part is what's not working. I convert the image to grayscale, but when I "Save As" and ad ".gbr" at the end of the title, I get this error message; apparently I can't save .gbr files with grayscale. When I save through RGB mode (my brush is completely black, I've tried "Desaturate") and load the brush, I can only color in black. Is there a way around this, or a fix?
