Our PowerPoint presentations are huge (>100 MB) due to large embedded
JPEG files. We will use the helpful suggestions given by group members
for reducing the size. In the meantime, however, we noticed a curious
thing: The first time we run "Slide Show" we find, not surprisingly,
that each slide takes about two full seconds to show on the screen.
However, if we scroll through the slide show once and then run "Slide
Show" a second time, we find that the slides appear on the screen
instantaneously, no matter how large our files are.
Does anyone know why this happens? We speculate that PowerPoint
requires extra time to decompress the JPEG images the first time
"Slide Show" is run, and that the decompressed JPEG bitmaps are saved
in RAM, where they can be accessed immediately when "Slide Show" is
run the second time. Or something like that!
