[OpenLayers-Users] Strange bug (?) in OpenLayers 2.4rc3 vs 2.2

[Lance Dyas]

I might have exaggerated saying "quite a few" the numbers might not have 
been significant... but
some of my bosses favorite WMS's were being hit by the problem. This was 
sufficient for me to
change it and in some ways TNTmap is about being able to browse for and 
view via multiple clients
 pretty much any WMS. from 1.0.0 to 1.3.0+, so even errors in the 
servers should be compensated for if they can.
