I'm not so a newbie :))
Of course, it's not possible....
I digited an amount, and then clicked in next screen..if you make a try, in the second screen THERE ISN'T any choice, you can only click to confirm the auction....
Maybe my english isn't so good, and maybe you surely read many false alarms, but this is not my case...
If you reply telling me "it's happened, we can't do anything about it, live with it", OK, I'll do it...
But don't talk with me presuming I'm an idiot, thanks :)
