Well I'm sorry to disagree and think the man from Apple was right.
I have just reinstalled a clean version of Itunes once again and plugged in my Ipad.
Itunes opens and finds the Ipad and a symbol appears along the top. Some of the contents are listed under Devices but they exclude the Summary, Apps and Photos.
As soon as you click on the Ipad icon, Itunes becomes unresponsive and freezes.
I personally think that it is the latest Ipad update [which superseeds the Itunes update] has caused the problem and it is the software on the Ipad that is no longer compatible with Vista.
Your right in saying Vista is seriously out of date and I will now have to upgrade if I wish to continue making full use of the Ipad. But I would have preferred to do this at a time of my choosing not to be shoehorned into it by Apple!
