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