That's not quite right. David, are you using a non-cygwin perl,
like ActiveState? If that is the case that is likely your problem.
The system command probably uses command.com/cmd.exe to execute commands
and at least command.com does not wait for win32 gui processes to
complete.
If you are using a cygwin perl, my guess is that IE starts another
process
that is *not* mapped by cygwin. Try using lynx or wget.
