[Mapserver-users] Zoom extent problem

[Brendan W.]

I've been tinkering with this for days and can't figure it out.  I try
to zoom in, and I get a blank image returned, or if the scalebar code
is uncommented, then I get an error which says:
"msAddImageSymbol(): Unable to access file. Error opening image file
C:\Progra~1\Apache~1\Apache2\htdocs\scalebar."
 
So removing the scalebar just produces a blank resulting map, so it's
not a scalebar problem.
I've changed the map extent in the mapfile to various extents, which
will give me different inital startup extents, but then when I try to
zoom in, I get the error above.  Sometimes I can zoom in a few times,
then the error - this is dependant on how far I have set the extents
initially.  I don't have any min/max setup yet, so that isn't it.  
I have also tried different shapefiles, rasters, etc.  Is it a WMS
problem? Frustrated!  Any ideas?  I'm stumped!  Here's the code:
