Run a video (AVI) with embedded audio
Audio is OK via default windows device (but that's another problem

Whilst cue is running, alter the audio level using the pan/level controls in the main cue window, works OK.
Then clip on Save settings, you can't save the altered level, it's greyed out
This has been tried on WIn7 & XP on different machines with different ASIO sound cards, same result.
