Not a biggy but it had me confused for a while.
Make a mulch with say a File Player and an effect.
Automate something and turn on Looping.
Stop Play, stop File Player.
Close laptop lid to induce sleep. Zzzzz
Open laptop and on resuming play neither the Sound Out graphic nor the Automation transport graphic work although automation is happening and sound is coming out.
This may of course happen with any mulch not just the example, I've not checked.
I'm back To Mulch now it's on OSX and loving it :-)
