Thanks for the document you advised I read, however I had read that when searching for solutions.
The first sentence in the document says..
In Mac OS X, each user account has a separate, invisible Trash folder
I am the only user, however it is like there is a separate folder as when I logged on again this morning the trash has 5 documents in it from days ago. They were not there last night??? Now I can't delete them again. It just hangs and even when I try stopping the deletion it does not respond
Also when I try to eject my portable hard drive again just now it says it is in use - but it is not
I am suspecting it is since I updated the OS as this never happended before - not sure what to do from here but feeling frustrated
