Unable to click anything!

I just downloaded Scrivener and went to do the tutorial, however, when I tried to continue by clicking on the sidebar, it seemed to be registering it as if I was clicking within the text field. It will not allow me to click anything at all and therefore I cannot use it… I would love to use this software (and have spent money on it) but I cannot until I get this fixed.

EDIT:
I can get it to work when not in maximized view, so I am able to use it, however I would like to be able to use it maximized.

Are you using a special pointer device, e.g. a tablet? If so, try switching to a standard mouse or trackpad.

Yes I am using a tablet. Thank you. I will switch to a mouse right away.
