It seems to me that the popup window\'s height has a limit of 489 pixels.
If I\'m setting the body element of the popup to 600 pixels of height, then popup window gets a scroll
The popup should size to fit the (relatively positioned) content inside. Alternatively, you can set the height CSS property on the body of the your popup page to force it to a particular height.
You can also hide the scrollbar by setting overflow: hidden; on body.
