I installed a number of programs that I had on my iPAQ 4155 and ran into many lockups. I forced myself to hard reset the 6315 and get it running one program at a time. I have narrowed down the trouble makers to SPB GPRS Monitor

or Caligrapher

or Meeting Mute. I have it running very well at this point and I am afraid to upset the balance. I will let you know what I find as I get the courage to load them.
Peace,
