the 1/2 and 3/4 buttons when hit pre flop, in button position, both cause the 'Raise' button to click but then no chips are bet, the time out etc

ok cool no prob.. i just played a bit again and i can refine this a bit...
the 1/2 and 3/4 buttons when hit pre flop, in button position, both cause the 'Raise' button to click but then no chips are bet, the time out etc...
however if you hit 1/2 or 3/4 button and then change mind and just hit 'Call' it will be ok (of course then you arent raising...).
the slider seems to work fine as well as manually entering bet using keypad/keyboard...
