Thanks for the info, its usually Safari & mail that i use first so that fits with the network, although usualy Safari just reports no network.
I'll try a non network app next time and see what happens.
I searched for info on bouncing icons and didn't find any info on actions to take.
I'm a new switcher from a PC and turning it off always worked for a PC
What's the best course of actions to take??
Many Thanks Phil
