After seeing the bug fix for the previous display issues with the passage analysis tool I joyfully began playing with this today. Been working great, but now I have noticed that L4 beta 4.5 keeps crashing from the passage analysis.
Having used the word tree successfully I began to look at a couple of the other tools, as not really bothered before, I clicked on the cluster graph which loaded fine, but when I tried to switch back the the word tree L4 would crash.
I tried this a couple of times, before I thought..... ahhhh maybe if I work around it by clicking on something else. So I loaded up the passage analysis tool and clicked on the version river only for it crash again.
Here are my logs from the latest crash.... 1731.Archive.zip
Edit: Tried to reload passage analysis and try another workaround, and after the three initial crashes, outlined above, all seems to be working ok. Will monitor this and post logs if any more crashes occur
