A woman in the 3-shop told me to always disconnect by clicking on the disconnect link, and wait until it was done before closing the software or pulling the USB lead out. When I asked what would happen she said my laptop would get slower every time it happened. A week later and most sessions end with Explorer not being able to access sites, but 3's window says it's connected. When I click 'disconnect' it says 'disconnecting' for ten minutes then I give up waiting and close it from Task Manager (the only way) despite some warning with an exclamation mark. Should I bin 3 before my laptop grinds to a halt, or is it harmless or is there some fix?
