I use the default bets 3BB plus 1BB per limper.
But sometimes it puts in the wrong amount.
For example on 6max 200NL it should make it $6, however sometimes it makes it $67 which is really annoying when you have to click fast.
I made some big losses with this when I don't pay attention to the betsing TN puts in the box.
I'm using WinXP on a VM on MAC.
