hi, im new to this web site and honestly about a third grader in flexi sign pro 10! im not doing bad but no matter what i do i cant seem to make the paint brush work! i need to fill in a few gaps in my art work and i would paint them and as soon as i let loose of the mouse button the color would disappear! i even tried it on the white background and it did the same thing. i cant find anywhere in the help or online to explain what im doing wrong.... can anyone help please???
