Curious, I'm using Gruss Betting Assistant.
So you had $1.00 back bet at SP, is this right?
If so, then I'm missing out :(

Chrome,

A while back (about a year now I think) betfair hit up a lot of the botting software and told them they had to stop their software allowing less then minimum bets. Most of the companies complied.

I wonder if Gruss was one of them.

That could explained it, thanks Useless Bettor.
I'll look around and investigate.

No, I use Gruss, works ok

The back bet is not placed at SP Chrome - place it as a normal back bet (BACK-SP if using excel to place the bet) & the 'At in play' option should be set to 'SP', so in the Options-Preferences-General select 'Convert to SP' as the default action if unmatched before turned in play.

Stugots thanks for helping out Chrome Prince since you have the same software.

This is what the forum is about. Punters helping each other.

Its great to see.

Yes, thanks very much Stugots and all who offered advice.
