[OpenLayers-Users] IE problems with OL + dojo

[Eric Lemoine]

Hi.

The "missing tiles" syndrom is often due to setCenter executed too
early, i.e. before the map div has its final dimensions.

If Ext is still an option for you I'd recommend looking at GeoExt
(<http://www.geoext.org>), GeoExt includes a map panel making it easy
to have an OpenLayers map in an Ext panel and avoiding the types of
issues you're seeing.

Cheers,

Eric
