How can I get the content panes to load behind the scenes. I know the first time the user loads this stuff it will be the slowest but I add a bunch of bookmarks for each of our locations(800) and some bookmarks for districts as well for quick zooming. So this takes 30 seconds or so.
Any suggestions on how best to do this? Maybe a splash screen at the start and then when everything is finished loading it goes away? How do I do something like that?
