I had to implement sandboxing in ChronoSlider and unfortunately the Chronolings (which can control iTunes, Sleep etc.) stopped working due restrictions. I’ve already uploaded version 2.0.6 where I included temporary exceptions to allow some basic Apple Scripting, but it was rejected by the reviewer. I’m now trying to solve the problem with the review-team, so be patient!
The only solution for now is downgrade (via Time Machine) to version 2.0.4 or drop me a mail and I’ll send you an “App-Store-Free” copy of ChronoSlider 2.0.6 of course for free!
