Autoscroll & Time display frozen in play mode...

I hope someone can help me.
I’ve been working on a project for the past few days but suddenly when I hit the spacebar to play back the project the scrolling cursor doesn’t scroll with the playback, nor does the time code in the time display start. When I then hit the spacebar to stop playback, the cursor and the timecode jumps to the point where I stopped the project. Why has it suddenly started to do this? I can’t work out if I’ve selected an option or switched off a button accidentally. If anyone can help me, I would really appreciate it as it’s twisting my melon! :open_mouth:

OK, after completely shutting down Cubase then restarting it and opening my saved project, all seems to be back to normal. So weird!!
