I have used Impress from Libreoffice 4.x.x with great success. Recently I upgraded the computer system, and installed Libreoffice 5.2.5 and am noticing a problem with all the .odp files I made with version 4:
When I open one, the Libreoffice 5 banner displays as normal, then the file opens as expected. I can see all the slides down the left column. So far so good.
However, when I try to strt the slide show with F5, it disappears off the screen and a few seconds later, I get a Libreoffice Document Recovery window telling me to press “Start Recovery”. If I do that, it works for a few seconds and tells me recovery was successful, then it comes back up on the screen. But when I press F5 to try again, the same Libreoffice Document Recovery window shows up again.
I tried removing Libreoffice 5, and rolling back to 4 and the files all open fine. Reinstalled 5 and all need an apparent impossible recovery. Is Impress 5 normally not able to open files created with Impress 4? With the sheer amount of files I’ve created with Impress 4, I’d stay with version 4 forever rather than retype them.
