I haven't upgaded yet.
The previous version is my first installtion of VoxATC
I would sometimes wonder if my mike was being heeard,
or bad speech, etc., when I first installed it.
Win7 Speech Recognition- I sometimes noticed it would be off,
not really sure if it was because I was jumping back and forth to Speech,Microphone setup,etc.
I forget now if I had it set to ON, but now I have it in Sleeping Mode,
This seems to keep up with my jumping between outside dialogs,etc
I can't remember now if that was suggested in the manual or not,
but perhaps if you try that it might help?
