I'm attempting to place two Map Suite maps onto the same page. These maps are displaying markers over OSM map data and will eventually be pulling in details from a databound grid, however I'm currently populating the data in response to a button click. The problem I am having is that upon first loading the page, the markers are only visible on the second map; the markers on the first map only appear after you attempt to pan or zoom, at which point everything appears to work fine. The results are the same in FireFox, IE7 and Chrome.
I've attached a simplified example page which should demonstrate the problem. Is this a bug, or have I missed something blatantly obvious?
