Why can't I get 5 sec lead any more? I change the default to 5 and it changes it back to 7.

Hello David,
Thank you for your question about lead times. Please explain the steps to reproduce this problem and we can check into it. Are you talking about the pull-down changing from 5 to 7 before you add a snipe?
Let me know and we can take the next step in troubleshooting.

No I am talking about the setting for default lead time in preferences. For a long time I had 5s lead time and now it keeps changing it back to 7s when I put in a snipe amount after loading my watch list. It changes the default in preferences back to 7s also.

That's funny, it only happened with "5". You can set it to 5 now.
Offhand, a lead time of 5 is a good choice. It's better in the case of tie situations, when you want your bid to come in earlier than other snipers using less than 5 seconds.
