course do not forget to question yourself if using hacks for this is what you

nice solution.</FONT></SPAN></DIV>

transparency not supported in internet explorer<BR><BR></FONT></DIV>
<P><FONT face=Arial size=2>Hi all,</FONT> </P>
<P><FONT face=Arial size=2>Just figured out why Internet Explorer keeps coming
up with a blank map, but not sure how to fix it. It would appear that Internet
Explorer does not support the PNG transparency that mapserver outputs. So my
transparent vector layers come out perfectly white where there's no data.
Firefox does support it, though. In the screenshot you can see a normal tile
and a transparent tile next to one another. The tile comes out transparent in
firefox, but not in internet explorer. Has anyone else had this? And....
anything I can do about it?</FONT></P>
<P><FONT face=Arial size=2>Not sure of this is in Bugzilla. Seems bugzilla for
Ka-Map is down......</FONT> </P>
