sorry, didn't know that it works in single layout, so it's got to do with on start of second layout, or subevent with instance variable, here's the capx, take a look please, the "locked" appears briefly though it shouldn't as it gets destroyed on start of second layout:
hope that helps. cheers!
also, @ashley, can you give eta on next build? I've been waiting really badly for touch / button / text field bug to be cleared out of the way for me, this got me checking the download page at least a 100 times today.
