labeling along the line

[Gagan Bansal]

Hi

I am using MS4W - MapServer 4 Windows - version 2.2.5.
placing labels on road with ANGLE FOLLOW option but a few of the labels only 
are placed along the road, rest are placed staright horizontal or slant.

here is the  label :
LABEL
      COLOR  0 0 0
      FONT "arial"
      TYPE truetype	
      SIZE 9
      ANTIALIAS true
      #PERCENTAGE 1.0
      POSITION AUTO
      MINDISTANCE 200
      PARTIALS FALSE
      ANGLE FOLLOW
      MINFEATURESIZE 20
      OUTLINECOLOR 255 255 255      
 END    

is there  any other option available or where is the mistake.

Thanks & Regards
Gagan
