Size issue?

Hello everyone!

I’ve started using the Arcade theme because of its nice clean look, but I seem to be having problems here and there. The big ones are the “read more” in the blog section is unresponsive, and so are the thumbnails in a gallery.

I opened up Adobe Muse and inserted html code linking the wordpress site to a new Muse site, and everything became responsive! Yet, when I tried to fit the wordpress site to a full screen they became unresponsive again…

So it almost seems like things get buggy when you have a bigger screen size?

Anybody tech-savvy enough to figure this one out?
