If it takes time to press the record voicetrack button to when the record voice track screen opens, this usually means you have lots of old voice tracks in your system and it's taking time to find an available voicetrack filename.
You just need to come to this screen and delete all of the old stuff.
Every voicetrack listed will also show the date it was recorded. You can click and hold the mouse button down and drag the mouse down the screen selecting all of the voice tracks you wish to delete.
You can also select and deselect all. However you choose to select the voice tracks, simply press the delete selected voicetracks and they will be deleted.
Be sure not to delete any voice tracks that were recorded in the past several days as they may be for today or future days schedules.
