Hi all,

Weird problem today. I just upgraded my production server to MapServer =
4.2.

I have an application that uses the Rosa applet.  The png image of the =
map is appearing correctly at first (a map with the WMS demis server map =
with a layer of red points displayed on top), but as I zoom in, the =
colour of the points is changing!  It changes to black and then to grey =
and I can't see the points very well.  However, if I do a view source on =
one of these zoomed in images and then view just the image itself, the =
image with points appears as it should - RED points on the background =
wms image!

=20

Does anyone have any ideas as to what is going on? =20

Thanks,

Debbie
