They discussed this issue in another thread a while back. If I remember correctly, the issue is caused by the cache in the broker server....it stores your connection information for a certain amount of time (I think it's updated every 30 seconds?). When you disconnect/reconnect quickly, the initial info in the cache isn't cleared...so it thinks you have more cameras than you actually do, which results in the additional cells in iCam. 4x4 is the max, as 16 cameras is the max supported. Do you only have the issue when you click stop/start in icamsource? You might try closing icamsource for 10 minutes or so, then re-run it and see if iCam is back to the 2x2 format...and see if it stays that way (without clicking stop/start in icamsource). Hope this helps you diagnose the issue. If not, I'm sure the SKJM guys will respond soon.
