Single tile layers essentially default to 'reproject': true for the initial load, but are not set that way for tile updates (which go through the same code path as tiled WMS layers; only the 'init' is different). The behavior that your'e seeing on the initial load is essentially what I expect you would see both before and after the load if you switched 'reproject' to 'on'. -- Chris > Regards, > Jelmer > > > On Mon, Sep 28, 2009 at 03:49:02PM +0200, Jelmer Baas wrote: > > > Hello List, > > > > > > I've been fiddling with OpenLayers for a bit now, and I'm > > very impressed > > > with the results.
