Thank you monkey56657.
So 1,2 and 5 are PICNIC problems !
After a clean install I managed to get 8.04 to see the upgrade to 8.10
I think 3 is easily fixed, I will have to shop around for an answer
Ref 4. After tests from different OS's I am begining to think that the NXclient on Mac is just a bit buggy / not fully compatible with Snow Leopard
**** EDIT **** There is a known issue when using MacBook.

6 Confuses me slightly. If I can u/l at high speed to the Internet, why can't I upload to my domestic box at high speed. The data is held on the same disks? Perhaps I am just not picturing the disk architecture the right way.
Thanks again for your response
