A file called help.js has been overridden to define the height of all popups as 150px. If the height of the popup content exceeds that value, a scroll bar will appear to allow the user to view the additional content.
We have also modified popups.xsl and content.xsl to change the popup closing mechanism from the “mouseout” event of the link to the [X] link in the popup window itself. This allows a user to scroll and view the popup at leisure.
Note that this is a simple example, and the closing link has been added to the main body of the page with the assumption that no header/breadcrumbs will be displayed. You may need to further modify content.xsl or Page.asp to get the look you want.
