just finished the installation of an eval copy of Confluence and find the layout is broken.
* the browse and personal menus are both visible and do not hide
* the Quick search label color is black over a dark blue background
The layout issues seem to suggest a style sheet is missing or broken.
Also, ajax behaviors seem to all be broken. EX: Under Administration - > Support Tools, the Support Request and other sections never load the loading graphic displays but not content loads.
