Left Offset for Pop-up Windows
Provides for a left offset in pixels for positioning pop-up windows on converted screens. Â The offset is only used when the "window left" property is specified in columns, rather than pixels. Â The default value is 140 to allow for an Actions panel on the left side.
Examples:
// remove the offset
pui.leftOffset = 0;
// set the offset to 100 pixels
pui.leftOffset = 100;
