v8.1.22
Not sure if this has been fixed yet, but I found out the hard way that when editing a View without saving (yet) and then adding documentation to the View and Committing the doco addition will reload the View in the editor and thus destroy your unsaved work... 
3rd time re-doing this work today, the other time happened when the designer's jxbrowser crashed (which I believe is fixed now in later versions)
