Problem in zoomin with png/gif symbols

[Fawcett, David]

Try removing the minscale and maxscale from the point layer and see if they continue to work.  

I also see that the layer status is set to on.  Do you have a control on your template that tells mapserver to display that layer?  With status of on, you need to specify the layer name in the URL or post that calls the mapserver.  Try setting the layer status to default and see if that fixes the issue.

Subject: [UMN_MAPSERVER-USERS] Problem in zoomin with png/gif symbols
 
Dear all,
  i'm getting a weird problem with my mapserver application.
  I' m using a point layer and i'm trying to render it into the map using a GIF symbol.
  When i load the map in its full extent or zooming out (starting from fullextent  visualization) the symbols are shown and they scale correctly with the view scale.
  On the other hand, when i try to zoom in, starting from the full extent scale, the symbols desapear, while the rest of layers continue to be shown correctly.
  I tried to change some parameters but nothing changed.
  -i substituted the GIF with a PNG...but nothing
  -i setted up Maxscale and Minscale and i tried to change it several times, but nothing happen.
  - i setted up the Symbolscale  with different values, and the size of synbols changed according to the value i putted there, but once passed the fullextent scale, again the simbols desapear.
   
  So what's wrong in my file?????
  This is my mapfile extract:
