I\'m inserting a very basic Google map into my page and the zoom control and streetmap icon are not visible, however if I place my mouse over where they should be I can zoom
I'm thinking this might be a problem with the browser or the code within the page that you're embedding this map.
If I look at this simple hello world code, the maps controls show up fine. I geocoded this map to the same location as your sample, so its not anything to do with the location.
What happens when you use this sample?
