Not fitting on screen

I just started using Simba and I am fairly sure I have it all setup, I read all the tutorials on how to make it work. When I run a script or have it open the MSI screen it doesn't fit right. So what could be causing this because I really want to get this up and going?

Here is a picture to better help understand my problem:

See how it kind of cuts off the bottom part of the screen so I can't see the back button.

Any help would be appreciated, thanks!
