thank you Zipster.
Let me point out another trouble encountered minutes ago. I picked Sir Joseph Swan at last race today at Kempton, in the selection page the odds for the selection read different from the window where comments are entered : 5.5 and 4/1 respectively. Even in different systems of expressing odds these are not the same. Before confirming I went back to the selection page and the 5.5 was still there , I entered again to make the comment and find 4 again, I confirmed and that was the odds value in the Current Tips. The difference might not be considered substantial but I think consistency is important; I assume that an odds change will be the same in all instances of the site.
Sometimes the odds on the main page are slower updating than on the confirmation screen, the odds on the confirmation screen will be the correct odds which is what you would have received. We are aware of the sometimes contradicting odds but you should always get the correct ones when making the tip depending on whether they have shortened or increased.
