changing resolution can (currently) only be done in-program.
Try hovering over the right side of the screen to see if you see an pop-up saying general settings.
Click that and check the resolution, but you probably have to scroll down, since the order is a bit strange

I have no idea how you scroll down, all I see is the furry in the backround and the buttons on the top, I don't see any general settings button :(

*Edit
I re-read what you said and I assume you meant scroll down in the general settings tab, but I have no idea how to get to the general settings tab x.x

If you hover on the right side of the window, there should be buttons there, but for smaller resolutions those are sometimes hidden.

You should still see the tooltips of the buttons though and can click them, so find the button saying "general settings"

If that still doesn't work, could you upload a screenshot of what you are seeing?
And what resolution is your monitor?

Ahh! I finally got it fixed. Thank you, They were just past my resolution, but I managed to fix it, thanks for the help <3
