I installed irComm 2.0 and my firewall software tells me it's trying to send a packet to the network. If I allow this packet the computer just reboots. I guess I'll have to fall back to 1.2.1 for now. Just thought you should know.
I'm running Windows 2000 SP4. I have a SigmaTel USB IR adaptor.
do You have the problems (Reboot) with the 1.2.1 too?
