When I was able to stop laughing, <g> I had a look in the Prefs. There
are three, but only one relates to you as a User; it's called
com.apple.dock.plist and it's in User>Library>Preferences. It might be
an idea to try throwing it away; trouble is, you'll have to put
everything back in the Dock afterwards, I think.
Paul,
Brilliant!
Thankyou sooooo much.
I really thought I was going to be in for a very long night, extracting reluctant Jpegs, one by one!
What a relief,
Please let me buy you large quantities of beer sometime,
All the best
Simon
