I noticed a few of my listings were being set as '10 days > 1st bid' when I when I actualy want them all to be '10 days Immediate Start'.
It seems there's a small glitch when using Firefox (3.6.3) and the browser back button to return to the listing details form. It doesn't appear to be a problem in IE.
I know there's a big 'Go Back to Listing Form' button but not everyone will use it (clearly ).
1/ Load up a listing in Firefox that's been set up as 'Start Immediately' (I used 27068668 but it's the same on others as well)
2/ Click on the 'List Similar' option
3/ Make a mistake (set the Reserve price greater than the Buy Now for example)
4/ Click on the Preview button
5/ Click on the browser back button and note in the 'Start Auction' section the 'On First Bid' radio button is now selected
