Ever since the 1.2.3 XF upgrade, some of the dropdown features dont work. Example: When installing an addon or upgrading etc: When you hover over controls, the controls show up to the right and cuts off right where you see it. Cant even choose any of the options. Another one is the drop downs in the XenForo navigation, Such as Your User, Alerts, Inbox, etc. They no longer have a drop down when hovering over them.
