Not sure that I've seen that myself with my own jetBook Lites. I have over 7,000 files
on the SD Card and haven't noticed any indication of file indexing except when the card
is first inserted. A large document can take awhile to load or reflow when switching from
portrait to landscape, and each page turn will cause the indicator light to blink a few
times. I have recently come across a particular epub that was causing an annoying delay
on page turns, it was quite noticeable compared to a normal page turn. When I do run
across the odd ebook that acts up, it can usually be easily corrected by just running it
through calibre, using the "JetBook 5-inch" output profile.
Luck;
Ken
