OpenLayers Vector Features issue in IE

We are using OpenLayers Vector Layer with Features in our application. Everything works fine in FireFox, but开发者_如何学Go in IE we are not able to find vector layer on the map. We are using OpenLayers-2.9 version.

Is this a bug or else we need to add any patch to to the code?

What rendering methods did you implement. Old IE won't support canvas, you should specify fallbacks to VML http://dev.openlayers.org/docs/files/OpenLayers/Layer/Vector-js.html
