William,

Thanks for the suggestion.

1.  This file listens to map for defaultviewport_changed
http://www.mappingsupport.com/forum_post/kml_71.html
The event never fires and the map div remains hidden

2.  This file listens to mykml for defaultviewport_changed
http://www.mappingsupport.com/forum_post/kml_72.html
The event never fires and the map div remains hidden

The above two outcomes make sense.  The event defaultviewport_changed
is specific to KML files and apparently the KML viewport cannot
*change* until a KML viewport is first established.

I  also tried the event "bounds_changed"

3.  This file listens to map for bounds_changed
http://www.mappingsupport.com/forum_post/kml_73.html
The event fired 3 times
At one point something flashed on the screen
After the 3rd event a map with the KML data appeared

4.  This file listens to mykml for bounds_changed
http://www.mappingsupport.com/forum_post/kml_74.html
The event never fires and the map div remains hidden

#3 above is not satisfactory since my goal is to have nothing flash on
the screen until the map with the KML data  appears.

I also tried setting the initial latitude to 85 but that just produced
a screen where each tile held the message "Sorry, we have no imagery
here".  The KML never displayed.

Any other thoughts on what I might try to achieve my goal of having
the KML map appear on the screen without anything else first flashing
on the screen?

Gee, I sure wish I could listen to mykml for tilesloaded......
