(solved) PLINK error output not coming through STDoutRead()

After beating my head agaist a wall for a while, I final realized that "some" output from plink (connection refused and the prompt for caching an rsa key) does not come in through stdoutread(). I see in the sciTE console, but not in stdoutread() or stderrread(). All oher output is picked up just fine. Anyone know how to read this output or where it is going? Many thanks.

I've build a little number that sends bulk commands to Cisco switches using some of the plinkwrapper, here is the area where I'm missing the output I need on the last select case.

This is what I get in the SciTE console when I run it. But it is not showing out in stdoutread().

he server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa "baked potato"
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)

The reason I was not seeing this output is because it is error output and sent to the $sdterr_child handle which I did not create when I launched the process.
Sound confusing? Just do the following if you are having this problem. Put $STDIN_CHILD + $STDERR_MERGED in the last argument in the run function when you launch the plink process.
