had similar transparency problem before and solved it with the correct
OUTPUTFORMAT setting of the Mapserver map file. YOu did not show
your OUTPUTFORMAT setting in your map file but I assume that the IMAGEMODE is
RGB. RGB mode does not support transparency (check Mapserver
documentation <a href="http://mapserver.org/mapfile/outputformat.html">http://mapserver.org/mapfile/outputformat.html</a>)
. Yes, it is strange for even with that setting, transparency works in OpenLayers.
Anyway, make the following changes and add the following OUTPUTFORMAT setting
bellow in your map file and see if it works:</span><o:p></o:p></p>

<p class=MsoNormal>I'm displaying UK Ordnance Survey MasterMap vector maps
using OpenLayers, TileCache and MapServer. The maps display perfectly when I
use just MapServer ( <a

target="_top">MapServer.jpg</a> ), as well as when I also use OpenLayers.
However, when I add TileCache to the mix, the various symbol images are no
longer transparent ( <a
href="http://osgeo-org.1803224.n2.nabble.com/file/n5389483/TileCache.jpg"
