I'm trying out the new version of treomail, and I'm having trouble receiving alerts when new mail is waiting. When I got into TreoMail, the "Messages are Waiting" envelope is at the top, but it seems I should be presented an alert no matter what app I'm in, or if the screen is off. In 'Alert Preferences', I've checked to receive audible and vibrating alerts, but this never seems to happen. In 'Delivery Preferences', I've chosen 'Automatically, Every 15 Minutes, 24hrs/day'. Any help would be greatly appreciated.
