In the classes, especially the ones with the spells you get with domain, circle, etc. that have a popup box (purple words and some greens), the popup box will not show up unless the browser is open wide enough to fit the box. The popup box does not adjust to the size of the window it needs to appear in. It also is skewed to fit a certain way from the link clicked on as it it is latched to the popup link and can only position there. It will not shift even on a screen wide enough, but will not show up if it does not have the room to appear where it is anchored. I am using Chrome on Windows 8.1. I have a widescreen running at 1600x900 setup and find if I want the browser at half the width of the screen so I can have a couple things side by side, that can even be too small for them to pop up correctly.

I know this definitely is the case for the class area, I have not tested it in other areas yet. I just figured it out when seeing how things look at different window sizes and verifying all the links work in the classes.

Forgot to note this is with Chrome on Windows 8.1 with browser window resizing. =)
