And now
Issue #3 is fixed as well
Keeping navigation keys pressed now scrolls the book continuously, fast for UP/DOWN, a little slower for RIGHT/LEFT (PG-UP/PG-DOWN).
Engine is pretty much stable now. Any feedback on the extraneous character particularly ? is welcome ! (I met a page displaying garbage but that was when playing with a possibly corrupted .LDV, I'm not sure it came from the engine or from a wrong address in the LDV ToC...)
Cheers!
