Hi all,

I've stumbled on a problem in Mapserver 4.0 that has me puzzled.

I have a number of point layers in my map that utilizes TrueType font =
symbols. When displayed by themselves they display perfectly.

But as soon as I turn on _any_ polygon layer, the symbols disappear, and =
colored rectangles replace them.

Pixmap symbols are not affected, only TrueType symbols are.
Turning on Raster, WMS or LINE layers doesn't seem to influence the =
symbol display at all.

Using Mapserver (Mapscript) 4.0 on Windows 2000 running PHP 4.3.2
Layers are displayed using a CLASS/STYLE definition.
Polygon layers use the TRANSPARENCY setting (if it matters).
Output is JPEG to facilitate an orthophoto backdrop.

Has anyone got a clue to what's happening, and even better, how to =
remedy this behaviour ?

Sample from my MAP file:

LAYER
  ...
  Type POINT
  CLASS
    STYLE
      SYMBOL "MapInfo Symbols_37"
      SIZE 16
      COLOR 255 0 0
    END
    TEMPLATE void
  END
END
...
SYMBOL
  NAME "MapInfo Symbols_37"
  TYPE TRUETYPE
  FONT "mapinfo-symbols-unicode"
  FILLED true
  ANTIALIAS true
  CHARACTER "%"
END

Best regards / Med venlig hilsen
Lars V. Nielsen
