Hi, I don’t have a way to reproduce this for you, since it involves a bunch of sensitive financial documents that I can’t upload. However, I’ve noticed that when refiling documents via the See Also interface — something I do very often — it causes DT4 to crash very frequently: maybe every fourth document or so. This happened only very rarely with DT3, but it’s super often in DT4.
If there’s anything I can do to help debug on this side, please let me know.
