I've replaced the card with a fresh one - Sandisk Extreme II SDhd, 4 gigs.
It's better, but I'm still having troubles with SOME epubs.
"Page Error"
I've rebuilt all of them (using calibre 0.4.121) and to my best knowledge, they are consistent in formatting, save procedures, etc. The ALL open just fine in Sony's epub reading software, which, to my best reconnoitre, (sp), is the best 700 simulator.
PLEASE don't tell me I have a bad 700.......how else can I test it? Has anybody else seen this?
