Voice Command and Palm Wired Headset

[sritt3]

When I initiate Voice Command via the button on the headset the headset and microphone is disconnected when the backlight shuts off, the call is still active if you press a button on the phone and activate the backlight, just no audio from phone or headset. This does not happen if VC is initiated via the Media Player side button. Is anybody else having this problem? Any help would be greatly appreciated.
