Can someone help me out here:

For those of you that use Fixed Odds through the TAB website, do you get a notice in the bet slip saying "bookmaker is considering your bet, please wait..", or something along those lines?

On a couple of occasions my bet was not accepted, or at a reduced stake, then following this (almost every time tonight) they changed the odds straight after my bet (dropped them). All this only just happened tonight. Before this almost every bet went through unless it was a huge stake in which case I'd get a small notice saying "please try --x-- amount". Now I am getting different notices which are being reviewed by bookmakers..

Cheers.
