    I didn't see Science Guy mention procexp?  Um, hey, S.G.,
are you using Process Explorer?

    I remember the ProcExp bug, but it only happened when I tried to
show properties on a cygwin process.  I believe Mark released a
followup version within 2 weeks that fixed the bug.  It wasn't a
cygwin bug (at least not the one I'm thinking of).

    But... hey, SG, if you are using Procexp, have you tried
getting an recent version?

    Brian -- not sure I understand: some other program injects code
into the cygwin process and it's a cygwin bug that should be fixed by
a new snapshot? 

    Also, if it was fixed several months ago, would he need a snapshot:
are the snapshots that out of sync with the released version?
