Anatella is a pretty stable software but it can happen that it “freezes” when starting a very complex data transformation. Hopefully, this only happens when (re-)starting a graph execution in “interactive mode” (aborting a graph and running it again several times might let the engine in an incoherent state). Before executing any graph, Anatella always saves transparently on the hard drive your data transformation graphs so that you can quickly re-open them without losing any of your work, should something wrong happen.
This means that, if you see that something is not working as expected (i.e. Anatella is unexpectedly “freezing”), you can always click the 
button and re-open quickly your data transformation graph without losing time.
There are several ways of launching a graph execution: You can:
•Click the output pin of an Action.
•Click the 
buttons inside the toolbar.
•Click the “Refresh from pin” button inside the “Column chooser” window.
•Click the “dry-run” button of the 
CreateTable Action.
If Anatella freezes when launching a graph execution, click the button and re-open (instantaneously) your graph.
