Screen Size and Layout Problems

Hi, I'm posting a course in Learn.com that is created using Lectora and AICC, but I'm having a couple of minor problems:1. When the course launches in the LMS, the screen size is huge (nearly twice the size as what I designated in Lectora.)2. The text boxes in my header are shifting -- my page title text box appears about 20 pixels higher on the published page as opposed to how it appears in Lectora. 3. If my bulleted list flows down to a second line, the line is automatically indented in the published version for no reason.Has anyone experienced these problems before (particularly the first) and know of any solutions??Thanks for your help!Anne
