When i connect my 3660 to my PC using an infra red port , the PC identifies and loses the infra connection alternating between the 2 almost every 5-15 seconds .

If I try to open the PC Suite that was shipped along with the 3660 it says "Another Infra red device blocking operation"

There IS no device around that uses infra red.

Kindly help!

Is this a problem with the phone?

My Sony Ericsson T310 had no problem working with the same Infra red port on my PC.
