Created attachment 113471 [details] a study file Navigator works, but after opening the file 3 or 4 times, Navigator window will open but the headings will be lost. Once I copied file to a new one, it worked for a while then did the same. It will work in MS Word still. Twice it all locked up. I highlited a few rows to copy, and it lock up. It has done this twice. both times while navigator was open but not showing headings. Thanks a lot for such a great program. It works very well on my old machine. This isn't a must, but just thought you would like to know. I attached a copy of the file, it is just a personal study fill. Good luck.
Which LO version do you use? Last stable one is 4.3.5 (4.4.0 has just been released)
Following a private email I received from the reporter, I'll put this one to WFM. (at least with 4.4.0.3)
