This is typical Yahoo!
Translated - yep we know something is wrong, we won't tell our users and we have no idea when it will be sorted out!
What kind of response is that?
Maybe they are settling for 2nd place after all ;)
For what it is worth I think that the positions shown in the view bids tool is correct. I have checked a couple on Yahoo! & MSN and they seem to match up. However, if the figures are wrong in the DTC itself I cannot see at a glance which position a keyword is in!
