Super Strange ? Issue!

We have the most bizarre issue happening in our community. When we installed the application, we could type all the question marks (?) we wanted. But at some point after during a variety of fairly simple design changes, we lost the ability to type question marks in the tinymce boxes (the box I'm writing this body in right now). When we type SHIFT + /, the text box is deselected but starts right back up again when you type anything else. It only happens on Chrome, but not IE.

I've never seen anything like this. To make it more bizarre, we encountered it on both on dev and production servers - which were not cloned instances. They were fresh installs and the only thing that was copied over was the theme export.

What in the world is going on?
