FOLLOW UP: Can't declare multiple MAXSCALE's

[David L. Kriske]

I am still having trouble inserting multiple MAXSCALE statements in my map
file.  I have since tried compiling mapserver on a Linux machine and get
the same behavior when adding multiple MAXSCALES.  I have also tried
changing the units to meters as suggested.  Could it be a shapefile
specific error?  What other areas does the MAXSCALE function depend upon?

I'm running Mapserver 3.3.011 (also tried .012) compiled for NT 4.0 (using
the precompiled
one on the mapserver site).  For some reason, I am unable to declare a
MAXSCALE statement for more than one layer.  If I do, I get...

Mapserv.exe Application Error - The instruction at <big memory address>
referenced memory at "<another big memory address>". The memory could not
be "written"

Then Mapserver bombs and I get a CGI Error in the browser.

If I take out all but one (or all) of the MAXSCALE statements it renders
the map
fine.  I'm using the Maperserver Tutorial Example 4 adjusted to use my own
shapefiles.  I haven't tried running Mapserver on a Linux Box, is the NT
build buggy?  Here's my .map file if it helps.....

Thanks in advance for any help you may provide.  This seems to be a great
program in every other respect!
