DOCBOOK-APPS: ? Success of 1.55.0 chunk.xsl varies by windows logon?

["Billard, Trish" <trish.billard@hp.com>]

We've found a peculiar problem when using the docbook 1.55.0 stylesheets to process some XML source for HTML Help output.

When I log onto the Windows 2000 machine, and execute the batch file that calls the 1.55.0 stylesheets, things work fine.

When a different person logs on to the same machine and executes the SAME batch file, the transformation fails completely.  He gets lots of errors, starting with "Error at xsl:import on line 6 of file:/c:/Program Files/Saxon/docbook-xsl-1.55.0/html/chunk.xsl:
  Failure reading http://docbook.sourceforge.net/release/xsl/current/html/docbook.xsl: no more input"

When we execute the batch file that calls the 1.54.1 stylesheets, things work fine no matter who is logged on to the machine.

Looking at chunk.xsl in 1.55.0, I noticed that the import statements call out the whole http://docbook.blah blah blah, but the chunk.xsl in 1.54.1 uses import statments that only refer to the file name (docbook.xsl and chunk-common.xsl).  In fact, if I alter the import statments in 1.55.0 chunk.xsl to match the 1.54.1 chunk.xsl, his transformation is successful.

So, can anyone tell me why we get different results for the same operation when the only difference is our windows logon?  What should I look for in the user profile?  

For now, we're staying with 1.54.1, but I'm concerned we could encounter this problem in future releases of the stylesheets.  I'd like to get consistent results, regardless of who runs the transformation.

Thanks,
