?I have noticed that when SSA initially opens, the map shows white tiles
eg: wms derived aerials (raster) do not show until the map is moved and or zoomed in or out. Using the dev tools in IE the wms service show errors initially,
But then works normally when you zoom in or out, with the tiles appearing normally.
The wms aerials also appear fine if you change between your map configs, which to me says there is an issue with the initial JS loading order and or initialisation of services on initial page load.
This issue also happens if the browser page is reloaded.
Have you had any issues such as this?
cheers
