I have a table with 2 rows and 2 columns - which currently have 3 update panels (the third one spans 2 columns) One update panel changes what is shows, depending on events on both another panel and based upon what is in the update panel itself. This update panel consists of three panels, one with your map control, the others do not have a map control.

Your documentation reccomends that I not place your control in an update panel (even thought nesting of panels in general is allowed), so my question is how can I "toggle" between the three panels, without doing a complete post to the page, utilizing update panels with your Map showing?

As an update - if I remove it from the update panel, i get errors when I try to hide the Panel the map is in when the Async Post Back fires in another update panel.

If I leave it in the update panel, most of the time it works without issue. However, for one event, I get this error:

ScriptLoadFailedException... the Script ... contains multiple calls to Sys.Application.notifyScriptLoaded() Only one is allowed.

When I remove your control, it goes away.
