<DIV>Below is my code for when I hover over a specific layer and the popup
hotspot information is shown. I am trying to figure out how to only get one
popup to show at a time so that I can show them like tooltips and destroy the
existing one if another is shown. I have tried using if (infopop) or if
(!infopop) but this doesn't seem to work in the way I have this coded. If anyone
has any advice on how to destroy my popup when another is created thanks!</DIV>
