"For whatever reason, the device can go into suspend mode when open and running the Audio Recorder app. I find that rather annoying but my workaround isn't too bad."
Recording/multitasking works fine but my eDGe keeps on recording
without going into suspend mode. I don't know why yours is not.
You might connect a mini-USB cable: the device will not enter suspend mode. (according to the Help-file
)
