Opening Query documents from a previous release causes Logos to freeze and we lose the query because it is unusable.
We have tried to make the morph query documents compatible throughout the beta cycle updates. There may have been a case here or there on where there could have been a problem with the transition.
However, if you run into an issue after creating a new document, please let me know the details.
I lost all documents from earlier 7.x betas, but can report that the document from the last 7.1 beta is healthy (I hadn't run it for fear of losing it!).
I'm sorry about the document loss. If it's any consolation, the document format is much more stable since 7.1.
