navigation links inactive on FF

navigation links inactive on FF

when the icons on top are clicked the left menu bar disappears and the application has more real estate (which is fine). However none of the navigation links (on top) in this view are active. The only way to get back to the main view is by clicking on X to close the application.

browser: FF 2.0.0.7, Window XP SP/2; same behavior on IE 6.x
