I looked the options for Callout, but saw no remedy there. If I specify ImageSize->Full, then only the stick is showing up.
Thanks ahead,

P.S. Unrelated but needed: How do I search the list? If I search anything using the provided search box, then I get info from the Wolfram sites but nothing relevant from the list.
The positions of the Callouts are determined at first rendering, and the placements are not re-rendered when you change the size interactively. Specify the ImageSize explicitly (e.g. 800) should work
