tracking interprocess comms.

Hi,

I am trying to capture output that an app normally sends to other  
processes under windows operation.

I know that in the case of major M$ apps this will be my ole but I believe  
that in the more general case this must be by simulating keystrokes

I tried WINEDEBUG="+relay" but the output file filled the 1.7GB !! of free  
space I had before the app got as far at putting up the main window.

could s.o. advice on a more suitable channel to watch.

Many thanks.
