SLD pointsymbolizer externalgraphic trouble

Latest update is that I totally re-installed MS4W version 1.2.1
Same problem exists for version 4.6.
However, it WORKS with the 4.4 version in the package. SLD with pointsymbolizer using external graphic works with 4.4.
Bug?
How should I proceed? What should I test?

Well, I've confirmed that my approach for getting charts on a map using SLD, pointsymbolizer and externalgraphics will work because I tested it against DMSolutions server with my own SLD and graph: http://www2.dmsolutions.ca/cgi-bin/mswms_gmap?version=1.1.1&service=wms&request=getmap&layers=prov_bound,popplace&sld=http://devgeo.cciw.ca/ecesdi/sldpoint4.xml
However, on my own installations of mapserver, I can't get this to work. I get the provincial boundaries with no point layer at all.
I am looking in my apache error log and I see:
[Thu Jul 28 11:58:12 2005] [error] [client 127.0.0.1] msDrawMap(): Layer 5 (prov_bound), 0.015s\r [Thu Jul 28 11:58:12 2005] [error] [client 127.0.0.1] msDrawMap(): Layer 9 (popplace), 0.016s\r [Thu Jul 28 11:58:12 2005] [error] [client 127.0.0.1] msDrawMap(): Drawing Label Cache, 0.000s\r [Thu Jul 28 11:58:12 2005] [error] [client 127.0.0.1] msDrawMap() total time: 0.031s\r
This error occurs even just with only the prov_bound layer, no SLD. So - is it time for me to re-install mapserver 4.6 on my machine? Any other possible solutions?

Assefa,
I'm quite sure that mapserver is finding the appropriate temp directory to write to because I got an SLD with polygonsymbolizer and external graphic to work just fine, and an image called H1.gif appears in that temp directory and my map is symbolized properly.
However, I still can't get the same thing to work with a pointsymbolizer.
My intention is to try to get little graphs on a map using SLD, pointsymbolizer and filters so that a layer that has centroids of provinces for instance can have a different graph at the centre of each province.
What do you and others think of that approach for getting graphs on a map?
Can anyone suggest anything else?
Anyway, still need to get a point symbolizer working with external graphics. Attached is the sld that I'm using for points... I'm at a total loss. An SLD for polygons and external graphics works fine.

You can use mode=browse and that should create files in the tmp dir.
You need to set the template in the web object :
WEB
TEMPLATE "template.html"
template.html should exist but can be empy or have something like this
<input type="image" name="img" src="[img]">
