[ID 20000310.001] Backtick Failure under Windows NT (output getslost)

The output from backtick on NT  (`...`) isn't showing
up sometimes.

  o   Within my cgi, the output of backtick vanishes, but 
      if I invoke the exact same command from a stand-alone 
      perl program run from the console, the data shows up.  

      Yet... within the cgi, if I say

               my $dir = `dir`;

      all is well -- I get the output.   Strange!

      The command that's failing now within CGIs looks like this:

             my $cmd =  'C:\progra~1\interw~1\foobar.exe 123';
             my $output =   `$cmd`;


This didn't happen with an earlier perl build I did; I'm not
sure if I've done something wrong, or if it's an NT-perl bug.

I've enclosed the output of  perl -V  and my %ENV (see below):
Any thoughts/ideas/pointers greatly apprecited.


               Sincerely,
               - Jon Cox



PS:
  I saw some rumblings about something seemingly related to
  this on p5p  (Paul.Moore@uk.origin-it.com  & gsar@engin.umich.edu)
  but I didn't see a solution anywhere.
