Hi Jerry,

You've got me worried now! Do you know how banks and such like get
around this security loop-hole?

I'm also wondering how the browser decides if the fields entered
represent a Login and Password pair.

I'm thinking of using the approach of randomising the two field names
as suggested by Tony, but would the issue you've referred to still
apply?

Nigel
