[OpenLayers-Users] Label mis-align with IE9

Mon May 30 10:26:38 EDT 2011

Playing with http://openlayers.org/dev/examples/vector-features-with-text.html,
it seems that IE 9 does not align labes well in VML, depending on
doctype and compatibility mode. To make IE9 use the SVG renderer,
which will fix the issue, you have to use the <!DOCTYPE HTML> doctype.
