[PHP-WIN] exec/system/passthru ??????

[Josh Seward]

I am trying to open a program and leave it running in the background. The script will 
always hang until I close the program that it opens?

Here is my code

$result = passthru($command."& 1> output.txt 2>&1; print output.txt; &", $pass);

I have tried using exec() system() and passthru() all with the same effect?

Does anyone know how to do this?
I am running win2000!

Thanks, 
Josh Seward
