GPO and MNC music contributions

Hi Sherry and everybody!

Can anybody tell me how to save a file in Composer that consists of both GPO instruments and general midi instruments? When I try to do it, the file saves and reverts everthing back to MS GW Wavetable device in the staff setup.
Also, both Audacity and the Windows Sound Recorder (which both record 'as heard by') will not record if GPO Studio is open. So far, the only thing I can save are wave files through GPO Studio where only GPO instruments are used on every staff. Thanks for any help!
