Anyone using Arc with MW600? I've this BT from X10 time and it worked fantastic, except that it's not fully compatible, but other functions were fine! Now I started using it with Arc and I face a strange problem. Whenever I miss a call, the BT will show the incoming call (arrow with the number) and hang there even though the caller stopped calling. No further calls are made available in the BT and I've to restart BT and off and on the BT in phone as well to get it working again. This doesn't happen always but happens 2 out of 3 times.
