Hi ronni,

First off, I unplugged the AppleTV and let it sit for a while so that
everything had a chance to recognise that. So the AppleTV itself is now out
of the picture.

Then I used Console to monitor messages whilst I restarted iTunes, it again
locked up and I force quit - messages below:

---------------------------------


The Mac and ADSL router have been rebooted several times since the problem
started - BUT, to be sure, I restarted the mac and rebooted the ADSL router
- essentially the problem remains - I won't include the console messages as
they are functionally identical.

I then considered that the actual wireless network is created and run by the
Airport Extreme - so I opened Airport Utility and saw that it was flagging a
firmware update - which I initiated. The firmware was successfully updated
and the Extreme restarted. As I still had Console opened, I noticed this
message which may be relevant? (Although I do have iTunes set-up so that I
do have to sign-in to purchase and don't have the remember this box ticked -
so this maybe normal?)

Again I started iTunes and noticed that some of the console messages had now
changed - however when I switched back to iTunes (after watching in console
for a while) it still locked up. The console messages are:

---------------------------------

I'm assuming the various
>  kernel    AirPort: RSN handshake complete on en1
Messages are down to the new Airport firmware.

I also note that the:

Message has now disappeared - which I again assume is down to the revised
firmware.

However, the locking up problem remained.



I then started iTunes in Safe Mode - a new experience for me ;o)

This time iTunes started OK and started downloading various podcasts - at
this point, many of the console messages were as before (so maybe this is
normal):

---------------------------------

I then waited for some time and let iTunes finish all that it wanted to do.
I then refreshed the podcast catalogue - which resulted in a further 2
downloads.
I then successfully refreshed the iTunes U directory.
I then tried to update all apps and it got to the first app and brought up a
terms and conditions have changed dialogue - which I suspect is the dialogue
that I failed to copmplete when the initial problem started! This time I
accepted the terms and conditions and the app download commenced. However
only one app downloaded.
Went back to the apps pane and again went to download all apps and this time
it all proceeded fine.

SO FAR SO GOOD!

I then quit itunes and restarted it normally (ie NOT Safe Mode)

I successfully refreshed the podcast catalogue and the iTunes U directory.

I downloaded a new app.

I then quit itunes.

All without a problem :o)


Soooo...

So far all is good and it appears the problem is hopefully solved :o))


Thanks very much for your help and suggestions Ronni. I'll now go and read
some more about starting apps in Safe Mode ;o)



Cheers
