Pencil failures

So I recently downloaded Pencil to try out animating stuff as a hobby.

I downloaded version 4.4 onto a Mac with no problems getting the program set up and running. However, the first time I try to draw something, the image disappears as soon as I let go of the mouse button. At one point, I was able to render it visible by switching from one layer to another, but I’ve since been unable to do so again. I can’t change between layers anymore. I can’t add any keys no matter how many times I hit the add button, and while I can get the colors to appear properly, I can’t see what I’m drawing, and thus, can’t animate anything. I’d try deleting the program and reinstalling it, but I don’t wanna have to do that unless necessary.

You should try version 5.4 from download section
