It seems that the maximizeButton property works just fine when the OverviewMap is created within the main map, like here. When the OverviewMap is created in it's own <div> within the main map ContentPane, the maximizeButton doesn't appear to work even when explicitly set to true. I thought maybe my OverviewMap <div> was too small and the maximizeButton was being hidden, but I adjusted the size of both the OverviewMap and it's <div> and the maximizeButton just isn't there. For example, if I use the code for this sample but set maximizeButton:true it doesn't work.
I want to give users the ability to hide/unhide the OverviewMap and I want to be able to control it's style (i.e. -box-shadow, border, etc). Any ideas?
