Macro Browser display off page in IE

In IE 7 (not sure about IE 8) when in the create new page or edit page screen, when the macro browser is opened, only half of it is displayed at the very bottom of the screen. The other half is cut off. Scrolling the page does not help as the macro box remains stationary. Basically this makes the Macro Browser box completely unusable for anyone in IE. We are running Confluence 3.3 and Theme Builder 4.1.3. Below is a screenshot of the bottom of the browser demonstrating the issue.
