Arming speedbrakes and altitude callouts

Hello all,first of all: Congratulations to the PMDG team for their smooth working SU2 737NG.Secondly: You know, although something like the 737NG works as good as perfect, You always will find mistakes. My critics ist not for weakening the great performance of this aircraft.1. For arming the speedbrakes for me "shift-/" does not work any longer. I have to arm them in the throttle panel by mouse clicks.2. For example, when doing touch-and-go-exercises or when doing a second flight without any pausing of FS, the altitude callouts are not to hear.Am i doing something wrong ?Some help would be greatly appreciated.Regards,Wolfgang
