Wavelab 9.5 auto playback on master section bypass

Hi All, Just updated to 9.5 from 9 and have one thing thats been driving me nuts.

On version 9, if i was playing back one audio file (or montage etc) through the master section, if i switched over to view another file (a reference track for example) and bypassed the master section it would auto play at wherever the cursor was in the new audio file. (hopefully that describes things well)

This no longer seems to work with 9.5.4 or 9.5.5. but perhaps im missing some little checkbox or setting somewhere.

Also, perhaps related, dragging plugins around in the master section (to reorder etc) now seems veeery sluggish.

Anyone else experiencing these?
