Solution to "restore windows" crashes
For those experiencing the frustrating crash every time you launch Angry Birds and OS X says something about restoring windows….
I solved the problem by going to my Library/Saved Application States folder and deleting the com.rovio.AngryBirds.savedstate folder. I hope this helps others…because Rovio sure hasnt bothered to!
