There was a post in between the kat's and my first one from somebody that I can't remember that explained in some detail that it was impossible to advise without knowing which browser/OS/platform was being used.

My subsequent post gave just one example of how the advice given would not apply.

Across the evening sky
All the birds are leaving
But how can they know
It's time for them to go?
Before the winter fire
I will still be dreaming
I do not count the time
For who knows where the time goes?
