[OpenLayers-Dev] [crschmidt@metacarta.com: [OSM-dev] Faster Commercial Layers]

[Erik Uzureau]

So Im running this example over again today and now it seems like it
*is* working.

Can anyone out there on the list run this:

http://openlayers.org/dev/examples/smoothDragging.html

in IE6 and or IE7 and verify that it's ok?

thanks up front,
e

ps. if you're getting a gmaps error, that should go away shortly....
i've updated the html file in svn but sometimes it takes a while to
get propagated
