As you can see the vertical alignment on the 4.x download page isn't right.
For example "Beginners Guide:" is visually tied to the link above rather than the link below it.
This is Safari on Mac. But if the 5.x page can work fine, I think the same code/style can be applied to 4.x as well.
The side menu on the 5.x Download Page - https://devstudio.jboss.com/download/
