IP Communicator version 2.0(2) was running on Dell 420 Laptops without any problems. Have gotten some Dell 620 Laptops, used a image to load software so that the only difference is the hardware. Now, after starting IP Communicator, the laptops will either Blue Screen or Freeze. This can occur immediately or 5 days later. If you don't start IP Communicator then no problems. Never had this issue on the Series 420 laptops. Anyone heard of this or have any ideas?
