+ | Root-files can be the source of various problems. | ||
+ | Usually they are caused by hidden changes in the internal state of ROOT. | ||
+ | ROOT stores the active directory and uses this to create new objects and look for existing ones. | ||
+ | The active directory is changed when a new file is opened. | ||
+ | This can lead to unexpected behaviours and hard to trace bugs. | ||
