I noticed Xojo 2016r1 stops compiling when your systems sleeps.
This wasn’t the case in previous Xojo version (or at least I noticed this now).
When compiling to 64bit it can take a long time (some of my projects compile for over 15 minutes). When I leave it compiling and come back after a while, I notice the compiling did stop and continues when the system wakes up again.
Appnap issues with Xojo?
