I take the risk to pass for someone mad but now I am sure there is a little problem. Something we can ignore but if there is really a problem, maybe report can fix it in his next release of texmaster. Everytime at the transistion 299-300 (>20G), it seems that the ARE is longer for the 1st tetrimino of the section 300-400. I have to anticipate it and stupidely wait to avoid the missdrop. Am I alone who can feel that ? is it the same for TI or TAP MASTER 499-500 ?
