Hello I have this problem a lot of times, sometimes my pen or brush is working normally -without brush with asterisk next to the line I am drawing, but sometimes just happens that it´s there and it´s making it also a bit harder to paint and do some things. I tried to look for this problem a lot but seems like it should be there but only when you want to start the line and I have it there all the time while drawing. When I dont have this problem the brush icon is not there and everything goes more smooth. Dont know if I explained it good enough, I also wanted to put screenshot but the paintbrush is not showed there, really dont know why, I also restarted my laptop and its still there. I am not advanced with illustrator so dont know what it can be, if someone can help me will be happy.
