I don't know if anyone has seen this, or know of a workaround, but I'm finding that if I zoom in too far with a Virtual Earth base layer, then the other layers are not plotted.
Eg. http://www.ecomapcostarica.com/map/map_test_ve.shtml ( I've found problems when trying to switch base layers between MapServer WMS and Virtual Earth. It will switch from VE to MPS perfectly, but not back again. My solution was to have two pages: one for each base layer. The above page is the draft version of the VE page) The default zoom (also duplicated with the Leaves and Lizards zoom option) plots at the maximum zoom that works. What you see is a KML layer, on top of a raster image and a 'stream' vector layer (both from MapServer WMS). No VE should be visible, but if you pan to the north VE should be visible. In fact we're zoomed in too far and VE shows the "forbidden camera" icon indicating that sufficiently detailed images are unavailable. This is to be expected. However if we zoom in one step further (eg. by scrolling the mouse wheel one click), then OpenLayers appears to 'hang' with the VE layer and does not show the other layers. This is actually quite limiting for this application, because virtually everything of interest will be plotted in the red KML polygon! So does anyone know of a workaround, eg. is it possible to make the VE base layer automatically appear and disappear when zoomed in very far? As an aside, the working non-VE version which uses public outline SHP data instead, can be seen here: http://www.ecomapcostarica.com/map/index.shtml We shall be in the field in two weeks time, and hope to update the map(s) whilst we're out there.
