Hi everyone! I am a bit new to Illustrator, and graphic design, but I've been using it long enough to know that the paintbrush tool is not working. Whenever I press on it in the tool bar, and/or press b, and it just gives me this symbol, and makes a line while I'm drawing, but the line goes away after. I've done a software updates for Adobe and my Mac, restarted Illustrator, restarted my computer, and it just doesn't work! FYI: it has the same symbol when I go into the pencil tool (I don't know if it is the right one for the pencil either.) HELP! Thank you!
