The preset bets that are put into the box are specifically the percentages that in 1-8 you will see on the betting2 tab where it says Preset bets percentages>>>>>> and the default raise preflop is a potsize raise automatically- the potsize raise key will give you a bet the size of the pot if you aren't facing a call so you shouldn't get a 0 and I just tested it with 1-8 and it's working fine so it's just your settings- probably the wrong currency setting. What does the money look like that you play with?
$10.00 $10,00 or 10,00 $ Look on the last tab, currency format, in order that I wrote they are decimal, comma leading and comma trailing
To set the default open Preferences.ini -for decimal (in order of the list below) you want 1,0,0,0 comma leading 0,1,0,1 and comma trailing 0,1,1,0

In 1-9 the GUI is layed out better. Your preflop raise will give you whatever in big blinds you enter plus limpers if you are facing a call of the size of the big blind, any larger it defaults to a pot size raise- make sense?
