[OpenLayers-Users] tilesOrigin distorts feature info on zoom

Thu Dec 11 03:41:53 EST 2008

tilesOrigin causes feature info to be off once i zoom in past 1:72k, what is
causing this?
I removed this witch makes the map work perfectly in firefox but ie does not
load the page.
is there any way to fix this? my bbox's are set to different for each
feature should i set 
all the features the same?

Here is the pagecode any help would be greatly appreciated....
