This issue may have been addressed but I missed it. I removed the battery and restarted several times but when I am on my pc with no other user its works ok, but if my wife uses her pc it comes to a complete stop. Any suggestions would be helpful. Also please note that several times a day If I read a article and rather take me to the follow up, I am taken to the 6602 Admin. page instead. and now my wife's pc is doing the same thing, and her pc has never been to the Admin. web site. I have removed the battery, sim card and reset the unit with no luck.
