Size of Storyline screen in Windows Explorer

Hello Articulate,

We have recently purchased Storyline, having used Studio 09 for 3 years.

When we view published Storyline courses, the course doesn't fill all the Explorer screen.  All courses published in Studio always filled the explorer screen.  Changing the Windows Explorer % view setting at the bottom right doesn't make any difference to the user experience.

I have tried changing some of the Template & Publishing setitngs without success.  I now seek your assistance so that the published course fills the Explorer screen. I have attached two screen shots below.  The first is from a draft course published in Storyline and the second a course published from Studio 09 using the same computer..

Thank you.

Mark
