One of the support people figured it out. Because my computer screen is small, my scaling was set pretty high. I decreased it to 150%, and Mocha works correctly now.
Okay, I will do that, thanks. Do you know where I can find my serial number or license string for Mocha AE? I need it to submit my case on their website.
Whoops, I meant to reply to you with my other comment. My computer fulfills all the requirements for AE, and I just updated drivers and the system. The cursor problem is still here, unfortunately.
