Summary Report PopUp Width Setting?

Summary Report PopUp Width Setting?

Hi.  I am using a summary report in conjunction with a normal list report.  When you click on a row in the list, it popup displays the associated summary report (invoice).

Is there a way to control the width of the popped up summary report.  It seems to fixed at 50% width of screen.  Has anyone found a workaround to display larger widths?

Thanks in advance.
