My brother the same thing is happening with you gets with me This indicates that the button down remains compressed on it I do not know why you separated the control man responsible for the bottom button and did not solve the important problem I took a bridge from the man control of the man responsible for this button and stopped its work but since the problem exists with you On the same version I have a 3D v6.1 I think the problem is not in control and we hope the brothers solve this problem with the hrf740 hottest problem
