Yes, for adobeviewer it boots up to the startup image I *used* to have.
Anyway, the fact you don't have to page forward means you get the headstart when the reader shuts down automatically, not just when you do it manually.
Still odd it doesn't work with the adobeviewer; I tried it with a DRM-free book just to make sure. And since you *can* screencap adobeviewer content...
Oh, well; another edge for fbreader.
