Thanks for your post.
I tried your suggestion to no avail. To let you know more, I tried what i
had spawning "cmd" instead of my target app and i get a console window with
no output and i am able to read and write to its standard input and output
with out any problems. With this app I still can see the out put and it
apears that it is not recieving any input and when i manualy try to input
data it does not work either.
Any Ideas? The only think i can think of is that it doesn't work on 16 bit
applications
