Some problems with resource images cocos2dx 2.2.0

Hello I’m having some problems making the migration to cocos2dx 2.2.0 at last i have made a complete build of the complete project.
I have solved it all but… there is a strange behavior once of each two when compile the project with the spritesheet resources, I will try to explain it with a sequence.

1 - Compile and build the project
All its ok the game is running
2 - I Don’t make any change and push the xcode play button again
some call to CCSprite::createWithSpriteFrameName(“background.png”) return NULL as if the image doesn’t exist.
3 - I Don’t make any change and push the xcode play button again
All its ok the game is running…

And so on.

I don’t understand it, it is possible that the resource file still open for some process? or something like that?

I have googled it and search in the forum and can’t find a solution or orientation. or maybe I don’t know how to make the correct question… All this ran pretty well in the cocos2dx 2.1.3 but since i have updated xcode and cocos…

Some idea?

Thank you and sorry for my english

I have make the resource file again with an update version of texture packer and it works all the time… I don’t know if there is some compatibility issues…

Regards
