I have created a simple slide show on my old XP desktop using Impress V3.1.1. It displays happily. The whole thing - pictures & odp file are all on a 32GB memory stick. When I plug the stick into my laptop (W10) & view & edit it on V3.4.1, I lose some of the pictures. The display just shows black or black with the slide link displayed along the top in red - not the actual picture. I get some pictures displayed. I also find that sometimes some pictures show & then later disappear! I need it to work on the laptop so I can show the pictures. I tried re-entering one of the pictures which seemed to cure it briefly, then the picture disappeared again!
If I look at Slide Sorter. a lot of the pictures will display, then lots go black, then some return & some stay black with the red link showing. I have re-loaded the program & I find that pictures that didn't show before show now, & different pictures don't show! The longer I work on the program, the more pictures seem to vanish. I've attached a screen shot of a particularly bad section. I don't think there's a memory shortage. All the pictures are jpg, varying from about 700KB to about 10MB. I have pictures that display (at the moment) of 8MB & others of of 1.5MB that don't.
Help please.
