[Geomoose-users] Poor quality WMS display in IE

[Brent Fraser]

Bob,

   Genius no, but I can be persistent.  This is really just a 
work-around.  If your users expand the layer name in the Catalog by 
clicking on it and use Fade/Unfade controls, the problem will appear 
again (unless you disable the Fade controls).

Best Regards,
Brent Fraser
