Just testing with Measure-21 and 8.2-765, yes I see this now. However
switching to any of the Neighborhood/Group/Home views does not seem
count as putting Measure into the background, it still consumes the
cpu and claims the sound input device. I'm guessing this is a Sugar
behaviour? Is this a bug or a feature (feels like a Sugar bug that
would make the UI sluggish for no go reason)?

Ahhh, thanks Arjun, so that's where they go to. I was expecting some
visual representation within Measure, perhaps like Record does, where
there is a tray at the bottom of the screen, or Browse and its
Is there a way to capture waveform images without the entire UI also
appearing in the screen shot?

Thanks, I understand this now as well. I had not noticed that new
entries were silently being entered in to the Journal. BTW: you can
resume the CSV file and Write will display the list of values. I also
tried copying the CSV to the clipboard, but it generated a blank
clipboard icon and would not paste anywhere (probably a Sugar issue,
the clipboard isn't very robust yet).
Some quick suggestions:
- The "Start Recording" text could say "Start Recording to Journal",
that would have pointed me to check in the Journal after clicking
- The time section menu could say "Every 30 seconds", "Every 2
minutes" etc. Before you explained, I believed that the times were the
duration of the sample to be recorded, not the interval between each
sample. The little toolbar interval icon makes more sense now that I
know what the menu does ;-)

Glad it was of use! I'm a bit of an electronics type, so I'm really
glad Measure is up and working again.
P.S. Any chance of solving the "keep error" bug every time Measure is
closed? I'm not quite sure what causes them.
