Cleanup: better nameing dialog box
Moved dialog 'div' to 'search_results'
Dialog box when no records are selected
Positioning of selection box fixed
The 'mouse' and 'position' jQuery UI libraries create conflicts

Apparently jQuery UI dialog doesn't like compression
Box draggable / result num instead of max if appropriate
