[OpenLayers-Users] OverviewMap - bad coords?

[Jeff Dege]

One more thing - looking at the properties for the tile image in the
overviewmap control that isn't being found, it has dimensions of
256x256.  Not the 200x200 I had specified.

So I set the tilesize in both OpenLayers and in KaMap to 256x256, and
now the OverviewMap seems to be working.
