Has anyone else found that using this code:

CF.activity().wifiEnabled = false;
CF.activity().wifiEnabled = true;

to disconnect/reconnect to strongest WAP can cause the 9600 to lock up and need a power cycle? Doesn't happen very often but when it does its always when its disconnected and says "Connecting" top left on screen.

This happens in multiple rooms with different WAPs so I doubt its the network. This even happens if a put a scheduleAfter in for the reconnect to give it several seconds between disconnecting and reconnecting. Also affects 2 different 9600's so I know its not a dodgy Pronto or firmware. Running latest versions of firmware on everything.

Any suggestions on how to avoid this? Anyone else seen it happen?
