Version 5.0.3. I did save the presentation manually several times so this should be ok.
In the left bar I can see all the thumbnails displayed correctly, but when I click on the thumbnails the actual slide on the right (in the larger field) is blank or misses half of the elements/pictures that I used in that slide.
I tried updating to 5.1
I tried restoring to previous saved version
I tried shutting down and restart, nothing works.
There is no failure message or anything. This is so windows, any suggestions?
