don't blame me it your PC 'hangs' if QRS is used in combination with other

Argo uses only the input portion of the sound card (technically speaking, only
the   waveINxxxx  APIs of the mmsystem subsystem).
I haven't specifically checked, but it is my impression that another program 
could
use the waveOUTxxx  APIs without conflict. This, of course, if the sound card
supports full-duplex (not every card does), and the properties in Windows for
the sound card are correctly set for full-duplex operations (not every Windows
installation is). But only a direct check can tell about the feasibility of the 
above.
