This is a new report.  A similar problem has been reported before but was 
only seen using the 4DOS replacement shell (but could also be seen on
Windows 2000 and NT).  

My guess is there is something broken in the way pipes are handled 
across VDMs - but no one has investigated when it's broken and why.

I would need to know more about the less and hello "native win32" 
applications.  I also can't reproduce anything like this quickly under
Windows 2000 so maybe it's something broken only in Windows XP?

Do you see the same problem with ls | more ? (ls is the djgpp image,
more is a built in win2k more.com image - but is actually a PE executable).
If this works it makes me suspicious of how the "less" image you have 
is handling the pipe.

New problem, try to investigate and tell us more.
