[OpenLayers-Users] OverviewMap - bad coords?

[Jeff Dege]

On doing some websearching, I found changeset 3087, which looks like it
might be a fix for the problem I'm seeing.  But it looks like 3087 was
included in 2.4, and I'm still having the problem.

I just DLed the trunk, and with that, I still have the problem.
