hey hey .... easy there tiger
I'm not saying anything ... but over the last couple of days you have posted quite a few questions ... no mention of them relating to MAC - I just assumed they were PC problems
2 monitors, sky/tv aerial, wireless connection, java, the google toolbar and the fact that you are unsure why IE8 isn't fully functional....
for some reason I got the idea that you were starting out -
(and there is nothing wrong with that - we all bin there)
rather than being confident in this area ....
if I'm wrong I apologise ... for the future I'll look forward to reading your answers as much as your questions
