OT-BASE Asset Center uses HTML5. Unfortunately, not all popular browsers have full support for HTML5 yet. In particular, issues with Microsoft Internet Explorer are on the record. If you experience display problems in the way that some page details don't show as in the screenshots that you see in the documentation, or if you get a warning during page load that a script takes too long to execute, browser problems are the most likely cause.
If in doubt, check if switching to Google Chrome solves any display problems.
