Space bar not stopping some songs

[Paddywack0]

Hi,
On most of my songs the Spacebar toggles between Play and Stop. But on some it will only Play, it does not stop the song when you hit it a second time. I cannot work out why this is happening. Anyone got any ideas?

This is Reason 8.3 on Mac Pro software only and with a Novation Launchkey 49 plugged into the USB. (P.S. The Play and Stop buttons on the Launchkey work as expected.)

Are you maxing out dsp usage?

Sussed it out. Space bar toggle stop/start is the default set up, but on some songs I had mapped Start to the space bar which meant the toggle stopped working. Simple but took me a while to suss it out. Clear remote mapping solved the problem.
