FOLLOW UP: Can't declare multiple MAXSCALE's

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?

--- previous message forwarded below ---

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!
