Hi, I have found that Spine Essential 2.1.09 freezes on OS X 10.10.2 if the loading window is focused. The loading stops at 98-99% and I have to force quit it. But if I focus another window during the loading process the program opens up correctly.
That's quite bizarre. What version is your Spine launcher? This is reported in the spine.log file, which you can find by clicking the spine.log button in the Setting dialog.
It's version 2.1.20
Seems to be a confict with RescueTime, http://rescuetime.com. I don't need to blur the loading win if I quit RescueTime.
Great you figured out there was a conflict! I wonder what Rescue Time could be doing!?
