Query: Problems with XP update SP2

Not always detected by XP. I had SP2 already installed and XP would not find the bluetooth device. I ran the installation CD more than 6 times! Right after installation it would work, but if you reboot it would not detect it. Sometimes, it would just work if I remove the adapter and plug it right back in. It kept pulling up the 'Driver Signing' dialog box. The instructions even tell you this is not licensed by Windows! I didn't think much of it until it created detection problems. I couldn't tell if at any given time the adapter was still connected or not. When it works its great though. No complains there (although I did have trouble getting Nokia PC Suite to work with it). Would be a great product if it weren't conflicting with XP update SP2. This product went right back where it came from. Going to look for one that XP will recognize.
