Why do LabTutor Panels appear distorted (e.g. table columns compressed, text cut off) in Internet Explorer?

The distorted display of LabTutor Panels is usually a result of having a 'Zoom' set in Internet Explorer that is not 100% (which is the default). LabTutor does not support a Zoom setting of anything other than 100%.
In order to reset the Zoom level from the menu bar in Internet Explorer, click on View, Zoom, and click on 100%
